Modeling with Inequalities: Visualizing Feasible Regions via Parametric Graphics

This GeoGebra example demonstrates how to build a mathematical model using inequalities and then visualize the resulting feasible region and its boundaries through graphical objects (curves/surfaces). The core mathematics includes inequality constraints, geometric representation of mathematical conditions, and the use of parametric or function-based graphing to depict edges and regions. The construction is organized around key objects—A, B, and pic1—which serve as the fundamental geometric inputs/parameters and the final rendered scene. Consistent with the lesson theme, the example also relies on transformation ideas such as translation and graph composition (addition/overlay) to combine multiple parts into a single clear visualization. Suitable for classroom instruction and modeling activities for advanced secondary school students through pre-university learners who want to connect algebraic inequalities to geometric understanding.
