Graphing Quadratic Functions - Intercept Form by Kristen Ehrler

This example demonstrates how to graph quadratic functions using the intercept form by inputting the y-intercept, axis of symmetry, and vertex. Key math concepts include quadratic functions, intercept form, axis of symmetry, and vertex coordinates. GeoGebra commands used are Textfield for input, Vertex for vertex determination, Polygon for shape drawing, and Intersect for intersection calculations. Suitable for middle school and above students to learn the geometric properties and algebraic representation of quadratic function graphs.
