Answer:
A, C
Step-by-step explanation:
The domain is the set of all possible x-values that will make the function work.
Here, m is the x-value (the independent variable).
The month number m is an integer, so the appropriate number type for the domain of r is integer.
The month numbers run from 1 to 12, inclusive, so the appropriate domain is 1 ≤ m ≤ 12.
