To determine the appropriate domain for the problem, we need to consider the variable \( t \), which represents the number of days after Annabel returns from the market until she bakes the banana bread. Since she bakes the bread 5 days after returning, the value of \( t \) will range from 0 to 5 days.
Thus, the correct representation of the domain is:
\[ 0 \leq t \leq 5 \]
Therefore, the appropriate domain for the problem is:
0 ≤ t ≤ 5.
