Which function has a vertex at (-1, -3)? A. F(x) = x+1+3
B. f(x) = x-1 +3
c. f[x]+3= x+1

x= 8 because 3x = 3 * 8, and 3*8 = 24

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.
