Step-by-step explanation:

Step 1: Define

f(x) = 4x + 1

g(x) = x² - 4

f(2) is x= 2

g(1) is x = 1

Step 2: Evaluate

f(2)

  1. Substitute:                     f(2) = 4(2) + 1
  2. Multiply:                         f(2) = 8 + 1
  3. Add:                               f(2) = 9

g(1)

  1. Substitute:                    g(1) = 1² - 4
  2. Exponents:                   g(1) = 1 - 4
  3. Subtract:                       g(1) = -3
