Here is the question:

The path of a flying disk can be modeled by the relation

h= -0.0625d(d - 112)

Where h = the height, in metres above the ground
and d = the horizontal distance, in metres

- - - - -

a) At what horizontal distance does the disk lay on the ground?

b) At what horizontal distance does the disc reach its maximum height

c) What is the maximum height?


Alright, so I understand that the horizontal distance is somewhere on the X axis, and vertical distance on the Y axis,
but how do you solve the questions using that?

Thanks in advance! :)
