a. do the arrows correctly represent the numbers that jessica is using in her expression? why or why not,

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.

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