Suppose the path of a golf ball follows the path graphed by the quadratic function f(d)= -1.6d^2+3.3d+0.2 where d is the horizontal distance the ball travels and f(d) is the height in meters of the ball at d horizontal meters. Find the maximum height of the ball: use the vertex, (-b/2a, f(-b/2a))

A.1.90 meters
B. 3.3 meters
C. 0.2 meters
D. 1.03 meters
