Parabolic Functions and Vertical Axis of Symmetry

This example demonstrates the geometric relationship between a parabolic function's graph and its vertical axis of symmetry. Key math concepts include functions, symmetry, vertex coordinates, and reflection transformations. It uses GeoGebra commands Vertex, Point, Mirror, involving objects like parameters a, b, c, the parabola, line, vertex, text, and points A and its mirror A'. Suitable for high school mathematics instruction to understand the fundamental properties and symmetry of parabolas.
