Write a formula for F o g o h, where f(x) =x+5, g(x) =4x, and h(x)= 2+x

Question

Calculus 1, need help please answer!

Answer 1

g o h (x) = 4(2 + x)

f o g o h (x) = [4(2 + x)] + 5

Answer 2

Hi Billy,

It might help to rewrite the composition in the form f(g(h(x))).

Then work your way from the inside out.

The first step would be to replace h(x) with 2 + x.

The 2 + x is now your input for the function g(x).

Hope this is helpful.
