Question

Which of the following will form the composite function G(F(x)) shown below?

G(F(x)) = 5(x - 7)2 - 4
A. F(x) = 5x - 4 and G(x) = (x - 7)2
B. F(x) = x2 - 4 and G(x) = x - 7
C. F(x) = (x - 7)2 and G(x) = -4
D. F(x) = x - 7 and G(x) = 5x2 - 4

Answer 1

G(F(x)) = 5(x - 7)2 - 4

I'm thinking that G(x) is a function that squares the values of x, multiples that by 5 and then subtracts 4.

G(x) = 5* ( ? )^2 -4


If F(x) = x - 7, then G(F(x)) =

G(x-7) = 5* ( x - 7 )^2 -4
