The water usage at a car wash is modeled by the equation W(x) = 4x3 + 6x2 − 11x + 7, where W is the amount of water in cubic feet and x is the number of hours the car wash is open. The owners of the car wash want to cut back their water usage during a drought and decide to close the car wash early two days a week. The amount of decrease in water used is modeled by D(x) = x3 + 2x2 + 15, where D is the amount of water in cubic feet and x is time in hours. Write a function, C(x), to model the water used by the car wash on a shorter day. C(x) = 4x3 + 4x2 − 11x + 8 C(x) = 3x3 + 4x2 − 11x − 8 C(x) = 3x3 + 4x2 − 11x + 8 C(x) = 4x3 + 4x2 − 11x − 8
