Step-by-step explanation:

Step 1: Define

f(x) = -4x² + 6x - 4

f(5) is x = 5

Step 2: Evaluate

  1. Substitute:                     f(5) = -4(5)² + 6(5) - 4
  2. Exponents:                    f(5) = -4(25) + 6(5) - 4
  3. Multiply:                         f(5) = -100 + 30 - 4
  4. Add:                               f(5) = -70 - 4
  5. Subtract:                        f(5) = -74
