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.
a. Find the quadratic function y = ax² +bx+c whose graph passes through the given points.
y = -16x² +60x+275
b. Use the function in part (a) to find the value for y when x = 5.
