The number of bacteria in a sample increased by a factor of 1.02 every minute from the time shown in the graph. the function shows the number of bacteria in the sample f(x) after x minutes from 9: 05 a. m:

f(x) = 10(1.02)x

exponential graph showing time in minutes on the x axis and number of bacteria on the y axis going through zero comma ten and approximately fifty comma twenty seven

which of the following is a reasonable domain for the function?
0 ≤ x ≤ 10
5 ≤ x ≤ 55
0 ≤ x ≤ 50
all positive integers
