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)*, 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. 0 ≤ t ≤ 4

Explanation: t represents time in hours and the scientist checks up to 4 hours, so the appropriate domain for t is from 0 to 4 (inclusive).
