Step-by-step explanation:

Step 1: Define

f(x) = 3x² - 3x + 1

f(-2) is x = -2

Step 2: Solve

1. Substitute:                    f(-2) = 3(-2)² - 3(-2) + 1
2. Exponents:                    f(-2) = 3(4) - 3(-2) + 1
3. Multiply:                        f(-2) = 12 + 6 + 1
4. Add:                              f(-2) = 19
