① This interactive example demonstrates the horizontal and vertical translation of the square root function y = √x, where students must plot the transformed function based on given shift amounts. ② Core math concepts include function translation (horizontal shift h and vertical shift k), the graph characteristics of the square root function, and the correspondence between the algebraic expression and its graph. ③ Construction highlights: GeoGebra commands such as If, Polygon, PointIn, Zip, and LaTeX are used to build the interactive interface; objects like startingPoints, usersPoints, and correctPoints track user input and correct answers; gPolyDotted and gPolySolid render dashed/solid polygons for visual checking; feedback, HowDidIDo, and TryAnother provide instant feedback and retry options. ④ Suitable for high school students learning function transformations, and useful for classroom demonstrations or self-paced practice to reinforce intuitive understanding of graph shifts.
