How to graph a quadratic in vertex form

This video tutorial explains how to graph a quadratic function in vertex form. It covers identifying transformations, plotting the vertex, and handling different values of 'a'. The tutorial also provides tips on plotting points and understanding the shape of the parabola, including how to reflect points across the axis of symmetry. The video concludes with a summary of key points for graphing quadratics in vertex form.

What should you do if 'a' is not equal to 1 or -1 when graphing?

Describe the process of reflecting points over the axis of symmetry when graphing.
