Asymptotes of Rational Functions

Explore the asymptotic behavior of rational functions with this interactive applet. ① This example demonstrates how to dynamically adjust function parameters to observe the changes in horizontal, vertical, and oblique asymptotes. ② Key math concepts include rational functions, asymptotes, and function graphing. ③ It is constructed using GeoGebra commands like Textfield, h, g, f, inputBox2, inputBox3, text1, text2, a, b, c, d, text3 to create an interactive interface for parameter input and real-time graph updates. ④ Suitable for high school and above students to understand function properties and graphing techniques.
