To define an appropriate domain for the problem, we need to consider the number of days Annabel has from the time she returns home with her bananas until she bakes the banana bread. Since she bakes the banana bread 5 days after returning from the market, the time \( t \) can range from 0 days (the day she returns) to 5 days (the day she bakes the bread).
Given this situation, the appropriate domain for \( t \) is:
0 ≤ t ≤ 5
This indicates that \( t \) starts at 0 and goes up to 5 days. Thus, the correct response is:
0 ≤ t ≤ 5.
