What do I have to know know to graph a quadratic in vertex form

The video tutorial explains how to graph a quadratic equation in vertex form. It begins by introducing vertex form and comparing it with standard form. The process of converting from standard to vertex form using completing the square is discussed. The tutorial then covers how to identify the vertex in both forms and how to plot the graph using a table and the axis of symmetry. Finally, it explains how the value of 'a' affects the direction of the graph.
