To find the maximum height just simply find the vertex of - 16t^2 + 64t + 3 and to find the axis of symmetry or the x value of the vertex do - b/2a or - 64/-32 = 2 in this situation. Plug in to get the y value - 16 (2) ^2 + 64 (2) + 3 = 67 Vertex (2,67) So the max height is 67 feet (takes 2 seconds to do so)
