Question

Calculate the following values
f(-1)
f(0)
f(2)

Answer 1

For f(-1), -1 < 0 so the first equation 8x-8 applies. 8(-1) -8 = -16.
f(-1) = -16

For f(0), 0 = 0 so the second equation 8x-16 applies. 8(0) -16 = -16.
f(0) = -16

For f(2), 2 >0 so the second equation 8x-16 applies. 8(2) -16 = 0.
f(2) = 0
