Question

A sporting goods store uses quadratic equations to monitor the daily cost and profit for various items it sells. The store’s daily profit, y, when soccer balls are sold at x dollars each, is modeled by y=6x^2 + 100x - 180.

Why is there an interval over which the graph decreases?

a. If the store sells more soccer balls, they can decrease the price.

b. If the soccer balls are returned for a refund, the store will lose money.

c. If the soccer balls are too expensive, fewer will be sold, reducing profit.
