Answer:
a.) 2
b.) 0
c.) ~ - 1.8
d.) 0
e.) -2
f.) 0
Explanation:
When they say f(-4) that basically means to put -4 in for x and find y. If they give the value of f(x) that is basically the y value and they want you to find x.
For letter c I put approximately -1.8 because when x = 3 that is roughly what y would be. See?
