A football player punts a football at an inclination of 45 degrees to the horizontal at an initial velocity of
70 feet per second. The height of the football in feet is given by the quadratic function
h(x)= -32x^2/
(70)^2 +x+4 WRITTEN LIKE THIS BELOW TOO if u were confused
h(x)= (-32x^2/(70)^2) +x+4
where x is the horizontal distance of the football from the point at which it was kicked. What was the horizontal distance of the football from the point at which it was kicked when the height of the ball is at a maximum? What is the maximum height of the football?
MAXIMUM??_____ MINIMUM???____
Maximum will occur at x = -b/2a = 1/ (2 ( 32/70^2)) = 4900/64 = x = 76.563 feet
Substitute this value of 'x' in to the h(x) equation to find the height at this point......
