7) A water balloon is launched into the air. It travels 20 meters horizontally and reaches a maximum height of 30 meters. Write the exact equation of the quadratic function that models the path of the water balloon. Use the form y = a(x - h)² + k a (x-10)² +30 (10,30) = Y 0 = 0 = 1000 + 30 a (20-10)² + 30
