x² - 2x - 8

Step-by-step 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

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

F (x) = x + 2 g (x) = x - 4 (f g) (x) =

2x - 2

x2 - 8
