Question

The number of bacteria in a sample increased by a factor of 2 every minute from 9:05 a.m. to 9:55 a.m. The function below shows the number of bacteria in the sample f(x) after x minutes from 9:05 a.m.:

f(x) = 10(2)x

Which of the following is a reasonable domain for the function?

0 ≤ x ≤ 10
5 ≤ x ≤ 55
0 ≤ x ≤ 50
All positive integers

Answer 1

wouldn't it be C?

Answer 2

cause its time so the domain has to be 0. and the minutes between 9.05 and 9.55 is 50
