Graph of Quadratic Function

This example demonstrates the graph of a quadratic function in standard form. Key mathematical concepts include quadratic functions, extremum points, and roots. Using GeoGebra commands such as Cell, Textfield, Extremum, Intersect, and Root, users can dynamically adjust the coefficients of the quadratic function and observe changes in the graph. Suitable for middle school and above students to learn about the properties and graph characteristics of quadratic functions.
