The appropriate domain for the problem, considering that Annabel bakes the banana bread 5 days after returning from the market, is defined by the time \( t \) in days that passes from the moment she notices the fruit flies until she bakes the banana bread.
Since \( t \) starts at 0 (the day she returns from the market) and goes to 5 (the day she bakes the banana bread), the appropriate domain is:
0 ≤ t ≤ 5
Thus, the correct response is:
0 ≤ t ≤ 5
