whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.

a.

step-by-step explanation:

a constant is a number without a variable, and m will always have a variable, therefore making m a constant. a term is just a part of an equation, so that makes any part of an equation always a term, so the answer will not be term.
