Graphing a quadratic by converting to vertex form

The video tutorial explains how to graph a quadratic equation by converting it from standard form to vertex form using the method of completing the square. It covers the steps to create a perfect square trinomial, factor it, and identify the vertex. The tutorial concludes with graphing the quadratic equation based on the vertex form.

How do you determine the vertex of a quadratic function from its vertex form?

Describe the relationship between the vertex and the graph of the quadratic function.
