Here are 5 problems I requested from my teacher for added practice and I wanted to try to solve them through here before I turned them in:
1. What is the range of the function f(x)=x^2?
2. For the following functions, find the value of f(5):
|x+2| if -4<x<1
4 if 1<x<3
-x+5 if x>3
3. Find the value of f(2) in the same functions given above^.
4. Determine the domain of the function:
2x^2-1 if 2<x<5
4-3x if 5<x<7
I will now post how I think it should be done and please take into account I'm not great at math:
1. {x|x not equal 0}
2. Unsure
3. Unsure
4. |x-2|<5
Can anyone help me please!!! thanks!
