Question 961174
the natural log goes to minus infinity
if {{{ x = 0 }}} or {{{ x = 1 }}} because
{{{ ln( 0 ) }}} = minus infinity
--------------------------
{{{ x }}} cannot have any negative value
because the log function cannot give you 
a negative result.
------------------
I cannot have {{{ x > 1 }}} because that
again gives me a log function that
results in a negative number
--------------------------
So, {{{ x>0 }}} and {{{ x < 1 }}} or
{{{ 0 < x < 1 }}}  is the domain
---------------------------
Here's the plot:
{{{ graph( 400, 400, -2, 2, -5, 2, ln( x - x^2 ) ) }}}
