24.4.3 Exponentials and Logarithms as Mirror Images

Core idea

One asks for the result and the other for the exponent, so the graphs of y=a^x and y=log_a x fold over the line y=x as mirror images.

Module goal. Establish the logarithmic function and its properties, revealing that exponential and logarithmic graphs mirror each other across y=x
