You can't simplify this...

You can graph it though.

Direction: Opens Up

Vertex: (-2,1)

Focus:(-2,5/4)

Axis Of Symmetry: x=-2

Directrix: y=3/4

(-4,5),(-3,2),(-2,1),(-2,1)

my answer is$ 12

step-by-step explanation:

because 15 -2=12

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.
