The path of a platform diver can be described by the equation y=-2x^2+15x+6, where x is the horizontal distance in meters of the diver from the edge of the platform and y is the height of the diver in meters above the surface of the water. In horizontal distance, about how far in front of the platform will the diver enter the water?
A)2 meters
B) 3 meters
C) 8 meters
D) 15 meters

Can you tell me how to figure this out? I do appreciate it!!! :lol:
 
What is the height y above the water when the diver enters the water? Plug that value in for y.

Solve for x.
