Final answer:
The function f(t) = -t - 3 decreases by 1 as t increases from -8 to -7.
Step-by-step explanation:
The original question asks how the function f(t) = -t - 3 changes over the interval from t = -8 to t = -7. To determine this, we can calculate the value of the function at the endpoints of the interval and then compare the results. At t = -8, the function value is f(-8) = -(-8) - 3 = 8 - 3 = 5. At t = -7, the function value is f(-7) = -(-7) - 3 = 7 - 3 = 4. Therefore, the function decreases by 1 as t increases from -8 to -7.
