Do you mean f of g as in f(g(x))?

I'm not sure what you are specifically asking...?

okay, so do you know what f(g(x)) = ?

No, but similar, think of f(g(x) as: anytime there is an "x" in the function f(x), replace the x with g(x), which is 2x

so its really: f(g(x) = 3(g(x))^2 + 2

which is specifically: f(g(x)) = 3(2x)^2 +2
