F ( x ) = 3 x + 2 − √ x − 3 find f(19)

Step-by-step explanation:

f ( x ) = 3 x + 2 − √ x − 3

f(19) = 3*19 + 2 -

      =  57 + 2 -4

       = 55

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.
