Question

Let f(x) = x + 8 and g(x) = x2 − 6x − 7. Find f(g(2)).

Answer 1

This is a "composite function" problem. Determine the value of g(2). Use this value as the input to function f(x). That'll give you the answer you want.

Answer 3

f(x)=-7

Answer 4

Let f(x) = x + 8 and g(x) = x2 − 6x − 7. Find f(g(2)).
First, evaluate the function g(x) = x^2 - 6x - 7 at x=2. Please show your work.
