Anais a math tracher noticed that the average grade on an exam, G, given that n students watch the related video can be given by the function G(n)=50+1.5n.

95 - 1.5m

Step-by-step explanation:

G(S(m))=G(30-m)

=50+1.5(30 - m)

simplify

=50+1.5(30 - m)

=50+45 - 1.5m

=95 - 1.5m

step-by-step explanation:

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.
