A soccer ball is kicked from ground level. When it has travelled 15 m horizontally, it reaches a maximum height of 20 m. The soccer ball lands on the
ground 30 m from where it was kicked.

Graph this information and use this to model the situation and with a relation in the form y = a(x-h)^2 +k
where the vertex is V (h, k).
