Graphing a Parabola with a vertical shift

The video tutorial explains how to graph the quadratic equation y = X^2 - 4. It begins with an introduction to the parent graph and then discusses the vertex form of a quadratic equation. The instructor demonstrates how to shift the graph down by 4 units, explaining the role of the K value in the vertex form. The lesson concludes with a reconstruction of the graph and a Q&A session to address student queries.
