Write the equation of the quadratic function whose graph is a parabola containing the given points.An egg is thrown upward from the top of a 128-foot-high building. The ball is 224 feet above ground level after 1 second, and it reaches ground level in 8 seconds. The height above the ground is a quadratic function of the time after the ball is thrown. Write the equation of this function.
