Today in class, we started off with Ms. Hawn checking our homework. While she was doing that we we’re working on a warm up, which were on simplifying radicals. That helped me really refresh my memory on that. After that Ms. Hawn gave us a worksheet on solving inequalities. It was a little hard for me, but luckily I got to work with my group and they helped me out. The most difficult was the word problems, but once Ms. Hawn explained it more to my group and I, it made more sense. After that we did that she gave us worksheet that was a little different to the solving inequalities worksheet. We had to use absolute value for the word problems. We had to try to do 1-3 for our homework.

We went over our warm-up50 at the beginning of class. It consisted of review on synthetic division and putting it in formation so that it can be solved. the second half of the warm-up dealed with getting your x values and showing them on the number line pointing in the right direction. then we went over absolute value notes.on example showed (x + 3)=10 and how it has to be put into 2cases. so one problem leaves the equation equal to 10 and the other case equal to negative -10. then you check the equation by putting in the X’s in each case to check if it’s accurate. I liked the method of solving in algebraic form because it’s a easier form for me because I like equations and numbers when solving things. I didn’t really understand when entering it in the calculator and trying to find the two x value points and when doing this I get confused. we also solved two step equations with absolute value. we also broke up into groups of up to three to four. and went up to the board solving equations. by doing this, it helped allot of other people understand it better including me.

Took a test on Radical Equations and Inequalities. The steps for solving radical equations are as follows:
1. Isolate the radical
2. Eliminate the radical by raising to power of index
3. Solve for x
4. Check
The test was mostly comprised of these problems as well as some review questions. Most of it was pretty cut-and-dry. I may have confused methods when dealing with inequalities as opposed to equations.

Today in class we played a review game that was based on the game Family Feud. In the review game we reviewed radical inequalities, domain and range, equations, and transitions. The part that I had the hardest time with was the tranisitions because of remembering what each number in the equation stands for, whether it it flips, moves left or right, or up and down. After I was able to memorize which number or symbol stood for transitions were much easier. My favorite is domain and range.

Today in class we reviewed and took a quiz finishing up rational functions. In the beginning when we started rational functions I didn’t really understand them. Now after alot of practice I have a better understanding of how to solve them.

On Friday In Mrs. Hawns class we played a game of Jeopardy with the class that was really fun, because we worked as teams to get the problems done so it gave use a chance to help others, and to review for the up coming test it aslo taught me and some of my other peers things we did not know how to do. Some of the problems we had were quiet difficult, This was one of the ones i got lost in but now understand because one of my peers helped me, and explained it, was this one.
EX) (x^2-9) over 4 divided by (x+3) over 8 which becomes to (x^2-9) over 4 divide by (x+3) over 8, which then you flip the sign and it becomes (x^2-9) over 4 times 8 over (x+3), well negative three times positive three equals nine so you would change (x^2-9) into (x-3)(x+3) and still leave it over 4 times 8 over (x+3) so then you would cancel what was the same which in this case would be (x+3) and (x+3), so then your left with (x-3) and 2 because 2 goes into 4 and 8= (x-3)2.

Hi, this is lashonda and today in mrs. hawns 1st period class we took a on rational expressions & denominators quiz. But before that we did get time to review which i was pretty glad about. I think i did an ok job on because i sort of know the material. We also went over new types of rational expressions where at the end of factoring and all that you have to find the x value i think. I sort of understand it but i could use a little exra help in the long run.

In class today we continued our lesson on +/- rational equations ,only instead of having the same denominator for each problem there were unlike denominators in every example we did. In solving these equations with unlike denominators we first had to factor them by using the diamond method or simply factoring out each number that gives you the original denominator once multipied together.sencond, you look for the least common multiple (LCM), the LCM is the number that you get once the two denominators were factored out {when there’s two of the same numbers in each equation that was factored, then you only bring one down to the LCM}. Third, get common denominators of the LCM and multiply by the missing factor in each denominator. Once multiplied by the missing factor the denominator should now be identical, and everything can be added. last thing to do for the equation now is to factor your answer, cancel the like terms, and simplify if it needs to be. I do understand whats goin on in these problems im just having a hard time putting everything in order, and once that happens i lose focus and things start to get harder because now im completly lost.

In class today we reviewed using difference of two squares,trinomials,and also using four numbers when factoring in other words grouping. here are some examples of what we reviewed:
Step1: write down the problem.
2x^2 +3x -14
Step2: is to see if the problem has a GCF.This problem doesn’t have a GCF.
Step3:Next is tom set up the diamond but sense I can’t write the diamond out I’ll just put out the factors.
( x +7)( x -4)
Step4:Now you have to divide by the A term which is 2.
( x +7)( x -4)
2 2
( 2x +7)( x -2)
We learned something even newer. were going over something new called rational functions.
Here is an example of a rational function:
f (x) = 1 + 2
( x -4)
This is called a transformed function.
Now you have characteristics of the function.
Transformations: right 4,up 2
Domain: 0
Vertical asymptote:x = 4
Horizontal asymptote:x = 2
x- intercepts:(3.5,0) <- [2nd][trace] 2: zero
y- intercepts:(0,1.75) <- [2nd][trace] x = 0

We are learning about cubic functions, which are similar to quadratic functions except for a few details. The standard form of cubic functions is ax^3+bx+cx+d, they all have 3 roots, and the domain and range of cubic functions is all real numbers. We are also learning about modeling with cubic functions, which can be used to find the greatest volume made from a sheet of paper. We have also learned about synthetic division, which is a shortcut method of polynomial division. I find this the easiest because it doesn’t involve the calculator and it is a throwback to long division, which is something I remember completley. I still have trouble finding the real root of problems like y^3+27= 0, then using synthetic division to factor. Cubic regression is hardest for me, because I confuse it with quadratic regression.

We learned completing the square. Which I somewhat understand, but I am having some difficulty on it. We also learned about parabolas which i remember from algebra 1 and i can do some of it but my mind needs refreshing. I have trouble with some of the factoring. Please tell me i did this right.

Today in class, we first did the warm up which involved graphing an equation on our calculators and finding the max or min and the x and y intercepts. It also had a review of factoring. Then we went over our homework and did some problems that we weren’t sure about. After that, we had a big discussion on how to find the x intercept using completing the square, which helped alot. After doing all of that, we used the whiteboards and did some problems and mrs. hawn checked them to see if we were doing them right.

Today, we learned about two new things: imaginary numbers and complex numbers which will help us solve more complex equations (no pun, intended). The imaginary number is defined by i = square root of -1. We worked on adding and subtracting expressions with imaginary numbers which was just like adding and subtracting radical expressions. The main thing was to focus on not mixing up negative signs and remembering to simplify and combine each term as much as possible. We also, used the imaginary numbers to define complex numbers as the sum of a real number and imaginary number. We worked with adding and subtracting these expressions. Finally, we worked on solving equations that required us to use complex numbers.
