You can put this solution on YOUR website!
$\"+x-1+\"$ cannot be negative. There is no log
\n" ); document.write( "which can result in a negative number.
\n" ); document.write( "There is an asymptote at $\"+x+=+1+\"$ at which point
\n" ); document.write( " $\"+y+\"$ goes to minus infinity.
\n" ); document.write( "For $\"+x+=+2+\"$ , $\"+f%28x%29+=+0+\"$
\n" ); document.write( "--------------------------------------
\n" ); document.write( "So the domain of $\"+f%28x%29+\"$ is $\"+x+%3E+1+\"$
\n" ); document.write( "Here's the plot:
\n" ); document.write( " $\"+graph%28+400%2C+400%2C+-2%2C+10%2C+-6%2C+6%2C+log%28+2%2C+%28x-1%29%29%29+\"$ \r
