Question

F(x) = x + 2 g(x) = x – 4 (f g)(x) =

2x – 2
x2 – 8
x2 – 2x – 8
x2 + 2x – 8

Answer 1

x^2 - 2x - 8

Explanation:

Answer 2

x² - 2x - 8

Explanation:

The notation (f·g)(x) means to multiply the two functions. Use the distributive property to simplify.

(f·g)(x) = (x+2)(x-4) = x² + 2x - 4x - 8 = x² - 2x - 8
