Hi,

I had a question about something I found in Mathematica 5.2...   I was plotting Log[x-1]-2 with x = {0,10} and y =  {-10,5} and strangely found that the graph crossed the x-axes at approximately x == 8  ...

It should be 101 of course, but it seemed like 8.   Then I did an Nsolve with the equation set to 0, and low and behold got an answer x == 8.38906.

Is this a bug in mathematica or am I missing something here?
