This example demonstrates the graph of a quadratic function. It involves the core mathematical concept of the properties of quadratic equations. Using GeoGebra commands such as Textfield, Point, OrthogonalLine, Intersect, Segment, etc., the graph of a quadratic function can be constructed. Suitable for high school mathematics education and learning.
