In the year 2009, the cost of a flat screen television can be modeled by the equation C = -10t+ 500 where t is the

number of years since 2009. Factor this cost polynomial. Note:

Use the ^ to express exponents, for example x^2.

Need help please

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.
