You throw a ball straight up from a rooftop. The ball misses the rooftop on its way down and eventually strikes the ground. A mathematical model can be used to describe the relationship for the ball's height above the ground, y, after x seconds. Consider the following data:

x, seconds after ball is thrown y, ball's height, in feet, above the ground
1 114
2 146
4 114

Find the quadratic function y = ax2 +bx + c whose graph passes through the given points.
A. y = -12x2 + 80x + 46
B. y = -10x2 + 60x + 64
C. y = -16x2 + 100x + 30
D. y = -16x2 + 80x + 50
