① This interactive GeoGebra example allows users to dynamically adjust parameters of an exponential function and observe how the graph changes in real time. ② Core mathematical concepts include the definition of exponential functions, the effect of the base a on growth or decay, the vertical scaling by coefficient b, and vertical translation by constant c, along with related ideas of derivatives and integrals. ③ Construction highlights: using the Textfield command to create input boxes (inputBox1, inputBox2, inputBox3) bound to objects a, b, and c, with functions f and g plotted dynamically, and text objects text1 and text2 displaying current parameter values. ④ Suitable for high school and early college students exploring function transformations, as well as for teachers demonstrating exponential behavior in class, providing a visual foundation for later calculus topics.
