Exponential Functions vs Logarithmic Functions
Loading the math board and drawing, please wait…
This example demonstrates the graphs of exponential and logarithmic functions, highlighting their inverse relationship and symmetry about the line y=x. Core mathematical concepts include exponential functions, logarithmic functions, inverse functions, function graphing, domain and range correspondence, and graphical transformations. The construction uses GeoGebra objects a, f, g, b, text1, text2, c, d, e, button1, and button2 to implement function input, text labeling, and button-controlled dynamic comparison. Suitable for high school mathematics instruction, classroom demonstrations, and independent exploration, helping students visualize the characteristics of exponential and logarithmic curves.
GeoGebra Commands & Parameters
Numeric a(2)f(x) = ln(x) / ln(a)g(x) = a^(x)Line b(-1, 1, 0)Boolean c(false)Boolean d(false)Boolean e(false)
AI Drawing Prompt Reference
Draw the exponential function y=2^x and the logarithmic function y=log_2(x) on the same axes, include the line y=x as the axis of symmetry, and add interactive toggles to show or hide each curve and the symmetry line, with text labels explaining the formulas and their inverse relationship. Include a parameter a initially set to 2 that determines the base of both functions, allowing the curves to update when a changes.
