Step-by-step explanation:

Step 1: Define

f(x) = 2x² - 4x - 3

g(x) = -2x² - 16

Step 2: Find f(x) + g(x)

  1. Substitute:                              f(x) + g(x) = 2x² - 4x - 3 - 2x² - 16
  2. Combine like terms (x²):        f(x) + g(x) = -4x - 3 - 16
  3. Combine like terms (Z):         f(x) + g(x) = -4x - 19
