Use the graph of f to evaluate the given expressions. f(0) and f(4)

Answer:
f(0) = 4
f(4) = -12
Step-by-step explanation:
f(0) means what is y at x=0
f(0) = 4
f(4) means what is y at x=4
f(4) = it is not shown on the picture
(0,4) and (2,-4)
As we increase by 2, we decrease by 8
with x = 2+2 y = -4-8
x=4, y = -12
f(4) = -12
