Graphs and Correspondence Rules - Task

① This interactive GeoGebra task presents multiple function graphs and correspondence rules (including parabolas, cosine functions, differential equations, squares, and median values) for learners to match, reinforcing the link between algebraic expressions and their graphical representations. ② Core mathematical concepts include function graph recognition, properties of parabolas, periodicity of cosine, solution curves of differential equations, square functions, and the concept of median value. ③ Construction highlights: from the summary, the activity uses GeoGebra commands such as Textfield, TableText, and LaTeX to display problems and options; it includes multiple function objects (g_1, g_3, g_4, g_6, f_1, f_4, f_8, f_6, f_7, f, g, h, i, j) along with buttons (button1, button2) and input boxes (InputBox1-4) for interactive answering and feedback. ④ Suitable for upper secondary or pre-university students learning functions, and useful in math labs or self-study to build intuitive understanding of the relationship between graphs and formulas.
