Okay I was going to do a great long spiel on this but i might save you the nightmare.
You should know what y=ln x looks like
so for y=ln(x-4) you just move the graph 4 units to the right (Yes i did mean right) To find out how many x units you would move the graph look at solving x-4=0
While I was at it I thought I would draw y=e
x and y=x
I want you to understand that y=e
x and y=ln(x) are INVERVSE FUNCTIONS that means that they are reflections of each other in the line y=x.
