FunctionProbability & StatisticsGraphing
This example allows students to evaluate functions by inspecting their graphs at random input values. Key mathematical concepts include functions and their graphs. GeoGebra commands used include Random, RandomElement, and FitPoly. Suitable for high school mathematics, particularly for understanding and applying function graphs.
