Algebraic Way to Find Inverses

Picture
The exponential and logarithmic functions are inverses of each other.  
How do we know this, though? Let's review the ways to find inverses using these two functions... (in the picture to the left)

The e^x function and natural logarithm function are also inverses of each other. Look to the left to refresh your memory on how to find inverses!

Graphical Way to Find Inverses

Recall that when we are taking inverses, we are just reflecting the graph over the line y=x
