Graphing Quadratic Functions by Garret Cahill (3)

This example demonstrates how to graph quadratic functions. Key mathematical concepts include quadratic equations, vertex, roots, and discriminant. Using GeoGebra commands such as Coefficients, If, Textfield, etc., you can dynamically adjust the coefficients of the quadratic function and observe the changes in the graph. Suitable for students at middle school level and above to learn the properties and graph characteristics of quadratic functions.
