Answer


(f\circ g)(x)=3x+3

Step-by-step explanation

The composite function can be rewritten as:


(f\circ g)(x)=f(g(x))

meaning that we have to replace all the x in f(x) with g(x).

In our case:

• f(x) = 3x

,

• g(x) = x+1

Then, we can write and simplify it as:


(f\circ g)(x)=3(x+1)
(f\circ g)(x)=3x+3
