Aprojectile is fired into the water from a cliff along the shore. the flight of the projectile above the water can be modeled by f(x)= -0.01x^2+0.764x+150, where f(x) is the projectile's height in feet above the water, and x is the horizontal distance of the projectile in feet from the base of the cliff.
a. how far from the base of the cliff(horizontal distance) is the projectile at its highest?
b. what is the projectile's maximum height?
c. from what height is the projectile fired?
d. what is the horizontal distance from the shore to where the projectile hits the water?
