You can put this solution on YOUR website!
The domain is all x which make f(x) defined.
\n" ); document.write( "This function is undefined when you have a division by zero.
\n" ); document.write( "This happens when $\"x-5=0\"$
\n" ); document.write( " $\"x=5\"$
\n" ); document.write( "So the domain is all x except $\"x=5\"$
\n" ); document.write( "In interval notation that would be
\n" ); document.write( "( $\"-infinity\"$ , $\"5\"$ )U( $\"5\"$ , $\"infinity\"$ ) \n" ); document.write( "

\n" );
