The average gas mileage m in miles per gallon for a compact car is modeled by m(s) = -0.015(s - 47)^2 + 33, where s is the car's speed in miles per hour. the average gas mileage for an suv is modeled by m(s) = -0.015(s - 47)^2 + 15. what kind of transformation describes this change, and what does this transformation mean?
