Question

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)Responses0≤n≤40≤n≤40≤n≤1040≤n≤1040≤t≤1040≤t≤1040≤t≤40≤t≤4

Answer 1

The appropriate domain is 0 ≤ t ≤ 4 (time in hours).

Reason: t represents time, which starts at 0 and is being checked up to 4 hours, so t can be any real value between 0 and 4.
