Answer:
In the explanation:
Explanation:
f(-10) means we need to find the piece so that x is also satisfied.
So we have x=-10 here. Which of your pieces satisfy that?
Well
so the first piece.
.
f(2) means we find the piece so that x is also satisfied.
So we have x=2 here. Which of your pieces satisfy that?
Well
so the second piece.
.
f(-5) means we use the piece that satisfied x=-5.
-5 equals -5 and the equals -5 part is included in the first piece.

f(-1) means use the piece so that x=-1 is satisfied.
-1 is between -5 and 5 so use


f(8) means use the piece so that x=8 is satisfied.
9 is greater than 5 so we use the third piece.

It looks like you have all the answers and you are trying to figure out why.
Let's do another problem.
What piece would you use if I asked you to evaluate:
f(-2)?
x=-2 satisfies the
so we use the


f(-6)?
x=-6 satisfies the
so we use the


f(7)?
x=7 satisfies
so we use


I will post the answers here after you had time to think about it.
