Quadratic Functions Different Forms Demo

This example demonstrates quadratic functions in various forms (standard, vertex, general) and their transformations with parameter relationships. Core math concepts include quadratic functions, vertex, axis of symmetry, geometric meanings of parameters a, b, c, and function graph transformations. GeoGebra commands used are Extremum for finding extrema, Intersect for intersections, and Line for drawing lines, involving objects like a_E, b, c, f, a_F, p, q, g, text2, text3, a_V, h, k, r, a, d, e, A, s, B, C, D, E, F, G, H, I, text6, text7, i, j, l, text4, text1. Suitable for high school mathematics teaching to understand properties and graph transformations of quadratic functions.
