Use the functions f(x) =3x+7 and g(x)=4x-2 to complete the function operations listed below. part a: find (f + g)(x). show your work. part b: find (f • g)(x). show your work. part c: find f[g(x)]. show your work.

F(x) = 3x + 7g(x) = 4x - 2

A. (f + g)(x)
     3x + 7 + 4x - 2
     7x + 5 <

B. (f * g)(x)
    (3x + 7)(4x - 2) =
     3x(4x - 2) + 7(4x - 2) =
    12x^2 - 6x + 28x - 14
    12x^2 + 22x - 14 <===

C. f[g(x)]
     3(4x - 2) + 7 =
     12x - 6 + 7 =
     12x + 1 <===

Ithink your answer is c mark me brainliest
