1) The equation below shows the height of a soccer ball, h(d) meter as a function of the
horizontal distance, d meters the ball travels until it hits the ground. The ball is kicked when
it is on the ground. h(d) = -0.025(d – 20)2 + 12
Always make a sketch to begin even if you are not asked to!
a) What is the maximum height of the ball?
b). What is the horizontal distance of the ball from the kicker when it reaches its maximum
height?
c) How far does the ball travel horizontally from when it is kicked until it hits the ground?
