Cubic Function Locus

This example demonstrates how to edit the algebraic expression of a function to match the locus of a constrained point. It involves core math concepts like function graphing, coordinate geometry, locus, and parameter constraints. The construction uses GeoGebra commands such as Point, Textfield, and objects like c, A, f, inputBox1 for interactive manipulation. Suitable for high school mathematics to understand the relationship between function graphs and loci, and the effect of parameter changes on the figure.
