Use the function in part (a) to find the value for y when x=5

You throw a ball straight up from a rooftop x, seconds after The ball misses the rooftop on its way down y, ball's height, in the ball is feet, above the and eventually strikes the ground. A thrown ground mathematical model can be used to describe 1 169 the relationship for the ball's height above the 3 161 ground, y, after x seconds. 4 109 a. Find the quadratic function y = ax" + bx + c whose graph passes through the given points y = -16x + 60x + 125 b. Use the function in part (a) to find the value for y when x - 5. When x - 5. y =
