Question

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 given data and solve, a. Find the quadratic function y = ax2 + bx + c whose graph passes through the given points.

b. Use the function in part (a) to find the value for y when x = 5. Describe what this means.
