Answer:
0 ≤ x ≤ 31
Step-by-step explanation:
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:
The reasonable domain of the function will be the number of days of the period when the population is explored. The research take place in October, this month has 31 days, thus, the reasonable domain is
0 ≤ x ≤ 31
Answer:
B) 0 ≤ x ≤ 31
Step-by-step explanation:
We are looking for a reasonable domain for the function, the domain is x which represents the number of days in the month of October. October has 31 days so x can't be greater than 31, and days can't be represented by a negative number. So, the reasonable domain for the function can't be greater than 31 or less than 0, so the answer is B) 0 ≤ x ≤ 31.
