Answer:

[tex]f(x) = x + 4[/tex]

[tex]g(x) = 3x^2 - 5[/tex]

Step-by-step explanation:

Given

[tex]g(f(x)) = 3(x + 4)^2 - 5[/tex]

Required

Find g(x) and f(x)

Replace all expression in bracket with x

[tex]g(x) = 3(x)^2 - 5[/tex]

[tex]g(x) = 3x^2 - 5[/tex]

The expression removed from bracket are:

f(x) and x + 4

So:

[tex]f(x) = x + 4[/tex]
