"find the value of g(f(x+1))", not certain this is properly asked. You need specific information about some numbers to find a value. Here is what we can do with those two functions about the composition.

From g(x), g(x)=x+3. We want to let x=f(x).
g(__)=(__)+3, put f(x) in the grouping location. .

We already have a definition for f(x), so we will use this expression:
. BUT THAT IS STILL NOT FINISHED. We are asked for not simply , but we are asked for . Then we want:



=
=
=
