Question

A scientist is observing a particular species of bacteria growing in a petri dish. The number of bacteria can be represented by the equation n(t)=50(1.2)^t, where n is the number of bacteria after t hours. If the scientist checks the population in 4 hours, what would be an appropriate domain for the problem?(1 point)
Responses

0≤t≤4
0≤t≤4

0≤t≤104
0≤t≤104

0≤n≤104
0≤n≤104

0≤n≤4
0≤n≤4

Answer 1

0 ≤ t ≤ 4

Reason: t represents time in hours from the start and the scientist checks up to 4 hours, so the domain is t between 0 and 4.
