Answer:

(fog)(x) = f(g(x)) = 3(x^2 + 1 ) + 2

Step-by-step explanation:

For this problem, you simply need to understand the notation (fog)(x) is equivalent to f ( g ( x ) ).  This means you simply plug the function g(x) into each x within the function of f(x).  Let's do this:

f(x) = 3x + 2

g(x) = x^2 + 1

f(g(x)) = 3(x^2 + 1 ) + 2

(fog)(x) = f(g(x))

Cheers.
