Taylor Rodriguez Reflection #4

This week flew by since we only had four days. Plus Mrs. Bandy was out two of the four days. I was so relieved to have our quiz on domain and range moved to Monday because I really didn’t get a chance to understand it since I missed the original day of the domain and range lesson. My plan for this coming week is to dominate. Haha. I plan to study hard and make sure I grasp the domain and range enough to fly though the quiz. As for the test on Wednesday, I will finish it. I refuse to go through my fourth test of this year still unable to finish it. I plan to work the problems by listening to my gut instead of my doubt. I’m going to quickly complete the problem and if it looks wrong but if I can’t exactly tell why I’m just going to move on and come back to it if I have time. I absolutely hate that I haven’t finished a test yet.
So I definitely understood the chapter four lessons two and three because they were pretty straight forward. I’m excited to say that I understand the process of finding the domain of a square root.
The steps were easy for me to memorize
1. Set equation under the root sign to zero.
2. Form a number line
3. Then using the values on either side of the number on the number line try with f(x)
4. Look for a positive answer.
5. Set up the intervals.
EX: square root of x+4
1. X+4= 0 therefore X= -4
2. ß--------(-4)---------à
3./4. F(-5)= square root -5+4 = Square root of negative one
5. (-4, Infinity)

What I don’t understand is how to find the domain an absolute value
I understand the steps for the most part but I get lost when I go to work problems
Ex: # 11 letter c
H(x)= / x/ - 2
Any help would be awesome
I think I just need a simple view on how to solve.
