Answer: C: 0 < x < 31
Step-by-step explanation: Because the < sign shows the line is going up towards the top. It starts from 0 and travels to the top-right to 31
A reasonable domain for this function to have would be 0 ≤ x ≤ 31.
We have f(x) as the number of fishes that are present in this water. The month is October and October has 31 days.
The x values is the maximum of the number of days in October. The minimum value is given as 0 because it is the population in the beginning of the month.
Hence we have 0 ≤ x ≤ 31
Which of the following is a reasonable domain for the function?
0 ≤ x ≤ 100
0 ≤ x ≤ 31
All positive integers greater than 100
All positive integers less than 100
