Suppose that the functions p and q are defined as follows.

p(x) = -x - 1

q(x) = 2x² - 2

Find the following.

(q º p)(-4) =

(q º p)(-4) =

Verified Answer :

Panoyin

p(x) = -x - 1
q(x) = 2x^2 - 2

(q o p)(-4) = 2(-x - 1)^2 - 2
(q o p)(-4) = 2(-x^2 + x + x + 1) - 2
(q o p)(-4) = 2(-x^2 + 2x + 1) - 2
(q o p)(-4) = -2x^2 + 4x + 2 - 2
(q o p)(-4) = -2x^2 + 4x
