f(x) = 3x – 7 and g(x) = –2x-6. Find (fog)(4).

Answer 1

(fog)(4)=-49

Explanation:

g(4)=-2(4)-6=-8-6=-14

3(-14)-7=-42-7=-49

Answer 2

The answer to your question is F(g(4)) = - 13

Explanation:

Data

f(x) = 3x - 7

g(x) = -2x - 6

(fog)(4)

Process

1.- Find f(g(x))

F(g(x)) = 3[-2x-6] - 7

Simplification

F(x) = -6x + 18 - 7

F(x) = - 6x + 11

2.- Find f(g(4))

F(g(4)) = - 6(4) + 11

F(g(4)) = -24 + 11

F(g(4)) = - 13
