Solve the problem.The following table shows the height of a football at various times during a punt.
Use a graphing calculator to find a quadratic regression curve that expresses the height in terms of the time. Use the regression equation to find the approximate number of seconds that it will take for the ball to reach the hands of the punt returner, who is 6' tall.
A. y = -16.38x2 + 71.45x - 2.52; 4.24 seconds
B. y = -15.96x2 + 70.21x - 3.51; -156.81 seconds
C. y = -16.38x2 + 71.45x - 2.52; -163.5 seconds
D. y = -15.96x2 + 70.21x - 3.51; 4.26 seconds
