FunctionCoordinate GeometryInequality
This example demonstrates the solution set of quadratic inequalities on a coordinate plane. It involves core mathematical concepts like quadratic function graphs, inequality solution sets, and interval notation. Construction highlights include using GeoGebra commands like Intersect, Point, Vector, and Text to draw function graphs, mark key points, and display inequality solution sets. Suitable for high school students learning the geometric meaning of quadratic inequalities.
