Answer:

f(g(5)) = 11

Explanation:

  • f(x) = x - 2
  • g(x) = 3x - 2

The composite function f(g(5)) is found by plugging g(5) for x into f(x).

Let's find g(5) first.

  • g(5) = 3(5) - 2
  • g(5) = 15 - 2
  • g(5) = 13

Next, plug this value for x into f(x).

  • f(13) = (13) - 2
  • f(13) = 11

f(g(5)) = 11.
