Substitution and Evaluation

Step-by-step explanation:

Step 1: Define

f(x) = -2x² + 4x - 6

f(2) is x = 2

Step 2: Solve

1. Substitute:                          f(2) = -2(2)² + 4(2) - 6
2. Exponents:                         f(2) = -2(4) + 4(2) - 6
3. Multiply:                              f(2) = -8 + 8 - 6
4. Add:                                    f(2) = -6
