Piecewise Functions and Geometric Transformations in Coordinate System

This example demonstrates how to plot piecewise functions in a coordinate system and construct and analyze quadrilaterals using geometric transformations. First, a piecewise function f is defined to observe its graph characteristics. Then, geometric transformation commands such as translation, rotation, and scaling are used to construct a specific quadrilateral. Key construction points include using the `Piecewise Functions` command to define the function f and the `Geometric Transformations` command for transformations. This example is suitable for high school mathematics education, particularly for learning coordinate geometry and function graphs.
