<u>Step 1: Define</u>

<em>Identify</em>

f(x) = x - 7

g(x) = x²

<u>Step 2: Find f(g(4))</u>

  1. Substitute in <em>x</em> [Function g(x)]:                                                                         g(4) = 4²
  2. Evaluate exponents:                                                                                        g(4) = 16
  3. Substitute in <em>x</em> [Function f(x)]:                                                                          f(g(4)) = 16 - 7
  4. Subtract:                                                                                                            f(g(4)) = 9

Answer:

9

Step-by-step explanation:

f(x) = x − 7

g(x) = x^2

Find g(4) = 4^2 = 16

Then find f(g(4)) = f(16) = 16 -7 = 9
