Question

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

Answer 1

The answer would be C because it is the function is increasing and the start is 100 so all domains must be over or equal to 100.
