Supposed the path of a baseball follows the past graphed by the quadratic function f(d)= -0.6d^2+5.4d+0.8 where d is the horizontal distance the ball traveled in yards, and f(d) is the height, in yards of the ball at d horizontal yards. find the initial height and the initial velocity of the ball. a. initial height: 5.4 yards, initial velocity: 0.8 yards vertically/yard horizontally b. initial height: 0.8 yards, initial velocity: 5.4 yards vertically/yard horizontally c. initial height: 0.8 yards, initial velocity: 0.6 yards vertically/yard horizontally d. initial height: 0.6 yards, initial velocity: -5.4 yards vertically/yard horizontally
