This example demonstrates how the graph and properties of a quadratic equation y=ax²+bx+c change as parameters a, b, and/or c are adjusted. Key math concepts include quadratic function graphs, vertex, axis of symmetry, roots, and discriminant. GeoGebra commands like Intersect, Vertex, and Line are used, involving objects such as a, b, c, p, yintercept, vertex, roots. Suitable for high school mathematics teaching to visually understand the impact of parameters on the graph.

GeoGebra Commands & Parameters

  1. Intersect(p, yAxis, 1) → yintercept
  2. Vertex(p) → vertex, , ,
  3. Intersect(p, xAxis) → root_1, root_2
  4. Line(vertex, yAxis) → axis

AI Drawing Prompt Reference

Draw a quadratic function graph, showing its vertex, axis of symmetry, and intersections with the x-axis and y-axis. Use sliders to adjust parameters and observe how the graph changes. The vertex is marked as the highest point, the axis of symmetry is vertical to the y-axis and passes through the vertex, the x-axis intersections are the roots, and the y-axis intersection is the y-intercept.
