Step-by-step explanation:

Step 1: Define

f(x) = 6x² - 2x + 2

f(-1) is x = -1

Step 2: Evaluate

1. Substitute in x:                    f(-1) = 6(-1)² - 2(-1) + 2
2. Exponents:                          f(-1) = 6(1) - 2(-1) + 2
3. Multiply:                               f(-1) = 6 + 2 + 2
4. Add:                                     f(-1) = 8 + 2
5. Add:                                     f(-1) = 10
