In the month of October, the population of a species of fish in a river increased by a factor of 1.05 every day. The function below shows the number of fish in the river f(x) after x days:
f(x) = 100(1.05)x
Which of the following is a reasonable domain for the function?
(a) 0 ≤ x ≤ 100
(b) 0 ≤ x ≤ 31
(c)- All positive integers greater than 100.
(d)-All positive integers less than 100
