Help learners recognize the characteristics of a quadratic graph and how changes affect them. An informative video uses a graphing calculator in order to find out what happens when the leading coefficient of a quadratic changes. The resource continues with showing by hand what happens to the points of the parent graph when undergoing a dilation.

Concepts

Instructional Ideas

• Pause the video to have class members guess what the graph will look like
• Have pupils graph the functions by hand to find the specific changes for the functions graphed

Classroom Considerations

• The class should be familiar with graphing quadratics using tables of values

Pros

• Concept video has a transcript
• The resource uses two methods to graph  technology and by hand

Cons

• The explanation for the concept video is not the correct one
