In this problem, we are interested in the growth of the number of fruit flies over a period of time, specifically from the time Annabel returns home with the bananas until she bakes the banana bread, which takes place 5 days later.
The appropriate domain for \( t \) (the time in days) should represent the time interval from when Annabel returns home until she bakes the banana bread. Since she bakes the banana bread 5 days after returning, we can define \( t \) as follows:
\[ 0 \leq t \leq 5 \]
This means that \( t = 0 \) corresponds to the moment she returns home with the bananas, and \( t = 5 \) corresponds to the moment she bakes the banana bread.
Now let's analyze the options provided:
-
0 ≤ t ≤ 256 - This is too broad since it includes times beyond when Annabel bakes the bread.
-
0 < t ≤ 256 - This is still too broad and excludes the time \( t = 0 \).
-
0 ≤ t ≤ 5 - This is the correct choice, as it captures the time from when she returns home to when she bakes.
-
0 < f ≤ 256 - This talks about the number of fruit flies, which isn't defining the time properly.
The correct option for the domain regarding the time \( t \) when Annabel is considering the number of fruit flies is:
0 ≤ t ≤ 5.
