Question

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

Answer 1

(fg(2)) = (f o g)(2)
Plug in 2 into the x values of g(x), then plug in the outcome into the equation for f(x).

Answer 2

solve g(2) that answer becomes the input to f(x)
use 2 in place of x in g(x) and solve
let's say you get Z as an answer, plug in Z for x in f(x) and solve
