Question
Annabel wants to make banana bread for the bake sale. She went to the market to buy bananas, and she noticed fruit flies after she returned home with her produce. The number of fruit flies grows at an exponential rate modeled by the equation f(t)=8(2)t , where f is the number of fruit flies after t days. Define an appropriate domain for the problem if Annabel bakes the banana bread 5 days after returning from the market.(1 point)
Responses

0≤f≤5
0 less than or equal to f less than or equal to 5

0≤f≤256
0 less than or equal to f less than or equal to 256

0≤t≤5
0 less than or equal to t less than or equal to 5

0≤t≤256

Answer 1

The appropriate domain for the problem, specifically focusing on the time in days from when Annabel returned from the market until she bakes the banana bread, would be defined in terms of \( t \), which represents the number of days.

Since Annabel bakes the banana bread 5 days after returning from the market, the domain for \( t \) should be:

0 ≤ t ≤ 5

So the correct response is:

0 ≤ t ≤ 5
