Step-by-step explanation:

Step 1: Define

f(t) = t² - 2t

f(-7) is t = -7

Step 2: Solve

1. Substitute:                         f(-7) = (-7)² - 2(-7)
2. Exponents:                        f(-7) = 49 - 2(-7)
3. Multiply:                             f(-7) = 49 + 14
4. Add:                                   f(-7) = 63
