Question

Let `f(x) = 7x^2+5` and g(x) = x-3, how do you find the composite function (f o g)(2)?

Answer 1

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 get`33` and now you have to find what`g(x)` is so you have to take `33` and you get`g(x)=33-3` and you get your answer
