Homework Answers
(a) This part is presumably about selecting the correct graph out of the given options. Since it is a cubic function with positive leading coefficient, thegraph would rise to the right and fall through the left. The most appropriate choice would be B
(b) In 2025, it will 25 years since the year 2000. Hence at x=25, y=10.4(25^3)-402(25^2)+5589(25)-8697=42278
(c)No. The function is a increasing function. The number of stores will go on increasing every year.

It is known that each store is approximately the same size and
carries the same merchandise. The geographic area from which a
store draws its customers is known as the customer base. One of the
variables is the percentage of the customer base who have graduated
