How to find the vertex
Depends on whether the equation is in vertex or standard form
Finding Vertex from Standard Form
The xcoordinate of the vertex can be found by the formula b/2a, and to get the y value of the vertex, just substitute b/2a, into the equation.
Finding Vertex from Vertex Form
It's called 'vertex form' for a reason! The vertex is just (h,k) from the equation.
