Minimum of Double Absolute Value Function

This example dynamically demonstrates the minimum value and its variation of the double absolute value function y=|ax|+|ax+b|. It involves core math concepts: absolute value functions, linear functions, inequalities, function minima, and geometric transformations. GeoGebra commands used include Text1, points A,B, Image1, slider a, and function f. Suitable for high school mathematics teaching to understand function properties and geometric interpretations.
