All values of $\"r\"$ are acceptable except those that make the denominator equal to zero since division by zero is undefined.
\n" ); document.write( " $\"r-1=0\"$
\n" ); document.write( " $\"r=1\"$
\n" ); document.write( "So in interval notation,
\n" ); document.write( "Domain : ( $\"-infinity\"$ , $\"1\"$ )U( $\"1\"$ , $\"infinity\"$ )
\n" ); document.write( " \n" ); document.write( "

\n" );
