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?

Option #1: 0≤t≤104

Option #2: 0≤n≤104

Option #3: 0≤t≤4

Option #4: 0≤n≤4

(1 point)
Option #

Answer 1

Option #3.

Reason: t is the time variable and the scientist checks up to 4 hours, so the appropriate domain is 0 ≤ t ≤ 4.
