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≤n≤1040≤n≤104

0≤t≤40≤t≤4

0≤n≤40≤n≤4

0≤t≤1040≤t≤104

Answer 1

Domain for the time variable t: 0 ≤ t ≤ 4.

Reason: t represents hours (can't be negative) and the scientist checks up to 4 hours, so t is between 0 and 4.
