Answer:

65

Explanation:

In order to find f(g(3)), we first need to find what is inside the parenthesis (it is obviously g(3) in the parenthesis, but if we find out what g(3)=, then we can use that to find out what f(x)=)

g(3)=3(3)^2+2

g(3)=3(9)+2

g(3)=27+2

g(3)=29

Now, we have g(x)=29

If we plug it into f(g(3)), we get: f(29)

Plug in again to find the answer

f(29)=2(29)+7

f(29)=58+7

f(29)=65

Thus, our answer is 65
