Make two shapes out of it.
The bottom is a rectangle 14 x 5 = 70 square cm
The top is a triangle 1/2 x 12 x 5 = 30 square cm
Total area = 70 + 30 = 100 square cm
Really i think it means to make a summary on how you do it ...
The values will be substituted to the respective functions and see if they equal to zero.
a. f(-4) = 0, f(-1) = 0
b. f(-4) = 512, f(-1) = 2
c. f(-4) = -512, f(-1) = -2
d. f(-4) = -8, f(-1) = -8
Therefore, A.
