F(x) = x+4
g(x) = 3x2 - 7

Find (f•g)(x)

3x³ + 12x² - 7x - 28

Step-by-step explanation:

Sorry I was talking to someone else here is the answer tho!Brainliest pls

3x³ + 12x² - 7x - 28

Step-by-step explanation:

(f • g)(x) = f(x) × g(x)

= (x + 4)(3x² - 7)

Each term in the second factor is multiplied by each term in the first factor, that is

x(3x² - 7) + 4(3x² - 7 ) ← distribute both parenthesis

= 3x³ - 7x + 12x² - 28

= 3x³ + 12x² - 7x - 28

step-by-step explanation:

if x = 2 you have to find x to finish the problem
