Answer:

Step-by-step explanation:
We have the function  and we have the function
 and we have the function  . We want to find g(x) composed with f(x)
. We want to find g(x) composed with f(x)
Then, the function (f o g)(x) is the same since f(g(x))
That is, you must do x = g(x) and then enter g(x) into the function f(x).


Simplifying, we obtain:

Finally. The composite function is:
