Extrema Identification Quiz for Functions

This interactive quiz helps learners identify local minimum and maximum points on function graphs. It randomly generates polynomial functions and displays candidate points on the curve, challenging users to determine which are extrema. The core mathematical concepts include local extrema (maxima and minima), polynomial function behavior, and criteria for identifying extreme points. The construction uses GeoGebra commands such as Polynomial to generate random polynomials, Min and Max to compute extrema, If and RemoveUndefined for conditional logic, RandomElement to select random functions and points, and Textfield for user input. It is suitable for high school or introductory college calculus students to reinforce their understanding of extrema and graph reading skills, and can serve as an engaging classroom activity or self-assessment tool.
