Plotting lg x and 10^x as Inverse Functions

This example visualizes how the logarithmic function y=lg x and the exponential function y=10^x relate as inverse functions, showing that their graphs are symmetric with respect to the line y=x. It focuses on key ideas such as inverse functions, the inverse relationship between exponential and logarithmic functions, and graph reflection symmetry on the coordinate plane. Construction-wise, GeoGebra uses the command “Invert” to generate the inverse function from the original function (using objects like f, g and points/parameters such as A, B and additional auxiliary objects). The mirrored graph provides an immediate geometric interpretation of how inputs and outputs swap when moving from one function to its inverse. Suitable for upper secondary through pre-university students, and for instructional use in function graphing and algebra.
