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)

O0<f<256

O0<f≤5

O0<t≤256

Answer 1

The appropriate domain for t is 0 ≤ t ≤ 5 (Annabel considers times from when she returns up through 5 days later).
(This gives the range 8 ≤ f(t) ≤ 256.)

None of the three given choices match this exactly.
