F(x) =3x; g(x) = 4x^2 +1 which expression is equal to (fog) (x)? a 4x^2 + 3x -1 b 12x^3 + 3x c 36^2 + 1 d 12x^2 + 3

D

Step-by-step explanation:

(f of g)(x) means to do f(g(x)). We will substitute g(x) into f(x) and simplify.

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
