Question 1115626: Express the given function h as a composition of two functions f and g so that h(x)=(f o g)(x), where one of the functions is 7x-3.
h(x)=(7x-3)^8
f(x)=
g(x)=
Please help :( I have no idea how to do this, thank you for your help

You can put this solution on YOUR website!
h%28x%29=%287x-3%29%5E8

Where do you find the function 7x-3? You see it used inside some function which looks like x%5E8.



h%28x%29=%28g%28x%29%29%5E3
Apparently g%28x%29=7x-3.

Looking outward, f%28x%29=x%5E8.
