write the quadratic function in the form f (x) = a (x-h)^2+k . then, give the vertex of its graph.
f (x) = 2x^2 - 12x +16
writing in the form specified: f ( x) = _
vertex: ( _ , _ )

step-by-step :

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.
