Question

Fred hits a baseball 3 ft above ground at a velocity of 100 ft per sec and at an Angle of 45 degrees with respect to level ground. The path of the baseball is given by the function f(x)=-0.0032x^2+x+3 where f(x) is the height of the baseball in ft and x is the distance from home plate in ft. What is the maximum height reached by the baseball?
