Graphing Quadratics in Vertex Form

The video tutorial covers the topic of quadratics, focusing on graphing quadratic functions in vertex form. It begins with a review of key terms such as vertex, x-intercept, y-intercept, and axis of symmetry. The instructor then explains how to graph quadratic functions using vertex form, providing detailed examples and emphasizing the importance of using graph paper. The session concludes with homework instructions and offers support through email and Zoom for any questions.

Why is it important to use graph paper when working with quadratic functions?

• It makes the notes look neat.

• It saves paper.

• It helps in accurately graphing complex functions.

• It is a school requirement.
