Is (0,8),(2,8),(-3,8),(1,8),(-4,8) a function

function is a process or a relation that associates each element x of a set x the domain of the functions

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1

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.
