the answer is g(x)=30

Explanation:

first you have to find what f(x) is in order to get g(x) so in order to get that, you have to first find what f(2) is and you do it like this:f(x)=7(2)^2+5 the 2 replaces x and you get33 and now you have to find whatg(x) is so you have to take 33 and you getg(x)=33-3 and you get your answer
