HELPPPPPPPPPPP!!!!!!!!!!!!!!!!!!

The population of a species of fish in a river increased by a factor of 1.05 every day for the amount of days shown in the graph. The function shows the number of fish in the river f(x) after x days: f(x) = 100(1.05)^x

exponential graph showing Time in Days on the x axis and Number of Fish on the y axis going through zero comma one hundred and approximately thirty one comma four hundred fifty four

Which of the following is a reasonable domain for the function days 0 to 31?
0 ≤ x ≤ 100
0 ≤ x ≤ 31
All positive integers greater than 100 Al
l positive integers less than 100

the reasonable domain for the function would be 0 ≤ x ≤ 31. This means that the number of days considered is from 0 to 31.
