Solve the problem.A football is kicked straight up from a height of 3 feet with an initial speed of 70 feet per second. The formula h = -16t2 + 70t + 3describes the ball's height above the ground, h, in feet, t seconds after it was kicked. Will the ball reach a height of 88 feet? Substitute 88 for h in the given formula and solve the equation. Are the solutions real numbers?
What will be an ideal response?
No, the ball will not reach a height of 88 feet. The solutions of the equation are 
which are not real numbers.
