A mathematical model can be used to describe the balls height above the ground, y, after x seconds. Consider the following data. x, seconds after the ball is thrown y, balls height, in feet, above the ground 1 224 3 176 4 104 a. Find the equation y ax2 bx c whose graph passes through the given points. b. Use the equation in part (a) to find the value for y when x 5. Describe what this means.
