"log" is short for "logarithm" .

This can probably explain better than I can: https://youtu.be/Z5myJ8dg_rM

 

Here's a simpler example of finding the inverse function:

 

f(x)  =  x + 1

                         Instead of  f(x) , let's say  y .

y  =  x + 1         Solve for  x .

y - 1  =  x

                        Swap  x  and  y .

x - 1  =  y         This is the inverse.

f-1(x)  =  x - 1
