The population of a species of rabbit triples every year. this can be modeled by f(x) = 4(3)x and f(5) = 972. what does the 972 represent?
the starting population of the rabbits
the population of the rabbits after five years
the rate the population increases
the number of years that have passed

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.
