The path followed by a roller coaster as it climbs up and descends down from a peak can be modeled by a quadratic function, wher
e h(x) is the height, in feet, and x is the horizontal distance, also in feet. The path begins and ends at the same height, covers a total horizontal distance of 100 feet, and reaches a maximum height of 250 feet. Which of the functions could be used to model this situation?
