The function best describes C(x), is 3x²+30x

Statement of equality between two expressions consisting of variables and numbers.

Given: R(x) = 3x² + 21x

number of coupons represented by, P(x) = 9x.

Now, number of coupons that are shipped out in any given week can be get by

c(x)= P(x)+R(x)

=( 3x² + 21x)+9x

= 3x²+30x

Hence, number of coupons that are shipped out in any given week is 3x²+30x.
