Step-by-step explanation:

Step 1: Define

f(x) = 4x² - 4x

f(-7) is x = -7

Step 2: Evaluate

  1. Substitute in x:                    f(-7) = 4(-7)² - 4(-7)
  2. Exponents:                          f(-7) = 4(49) - 4(-7)
  3. Multiply:                               f(-7) = 196 + 28
  4. Add:                                     f(-7) = 224
