You can put this solution on YOUR website!
the natural log goes to minus infinity
if +x+=+0+ or +x+=+1+ because
+ln%28+0+%29+ = minus infinity
--------------------------
+x+ cannot have any negative value
because the log function cannot give you
a negative result.
------------------
I cannot have +x+%3E+1+ because that
again gives me a log function that
results in a negative number
--------------------------
So, +x%3E0+ and +x+%3C+1+ or
+0+%3C+x+%3C+1+ is the domain
---------------------------
Here's the plot:
+graph%28+400%2C+400%2C+-2%2C+2%2C+-5%2C+2%2C+ln%28+x+-+x%5E2+%29+%29+
