Complete the square to graph a quadratic in vertex form

The video tutorial explains how to convert a quadratic equation into vertex form by completing the square. It covers the steps to ensure the quadratic term has a coefficient of 1, how to complete the square, and how to factor the resulting trinomial into a binomial squared. The tutorial also demonstrates how to identify the vertex and graph the function, discussing the graph's behavior and transformations.

Explain how to determine if the graph opens up or down based on the coefficient A.

Describe the pattern of the parent function from the vertex.
