Exponentials and Logs as inverses

Exponentials and logs as inverses

Move the tools and frame around to get an unencumbered view of the graphs of $a^x$ and $\log_a(x)$. Adjusting the slider will alter the value of $a$.

In each case we note that each curve is a reflection of the other in the line $y=x$ and hence $a^x$ is the inverse of $\log_a(x)$.
