Quadratic Functions (Vertex Form)

This example demonstrates the graph of a quadratic function in vertex form and how parameters a, p, q, c affect it. Key math concepts include quadratic functions, vertex, axis of symmetry. GeoGebra commands used are Intersect, OrthogonalLine, Segment to construct the graph. Suitable for high school mathematics teaching to understand the characteristics of quadratic function graphs and the meaning of parameters.
