**Properties** of the Vertex of a Parabola

- is the maximum or minimum value of the parabola (see picture below)
- is the turning point of the parabola
- the axis of symmetry intersects the vertex (see picture below)

#### How to find the vertex

Depends on whether the equation is in vertex or standard form

#### Finding Vertex from Standard Form

The x-coordinate of the vertex can be found by the formula $$ \frac{-b}{2a}$$, and to get the y value of the vertex, just substitute $$ \frac{-b}{2a}$$, into the

#### Finding Vertex from Vertex Form

It's called 'vertex form' for a reason!

The vertex is just (h,k) from the equation.
