Question

Let f(x) = x2 + 6 and g(x) = x + 8x g ( x ) = x + 8 x . Find ( f o g)(­ -7)

Answer 1

3975

Explanation:

fog functions are basically f(g(o)).

So for this problem, it would be f(g(-7)).

Plug in -7 to the g(x) equation first, and you should get -63.

Then plug -63 into the f(x) equation, and you should finish with 3975.
