Step 1: Define

Identify

f(x) = x/4 - 3

g(x) = 4x² + 2x - 4

(f + g)(x) is f(x) + g(x)

Step 2: Find

  1. Substitute in functions:                                                                                     (f + g)(x) = x/4 - 3 + 4x² + 2x - 4
  2. Combine like terms:                                                                                         (f + g)(x) = 4x² + 9x/4 - 7
