Question

MULTIPLICATION OF FUNCTIONS

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

(fg)(x) =

a. 2x-2
b. x^2-8
c. x^2-2x-8
d. x^2+2x-8​

Answer 1

for this one just set them to each other:
(x+2)(x-4)
then you can just multiply each piece together (x times x, x times -4, 2 times x, 2 times -4) then you combine like terms!! hope this helps,
