You can put this solution on YOUR website!
$\"f%28x%29=1%2Fx%2B2\"$ \r
\n" ); document.write( "\n" ); document.write( "the domain is all real numbers $\"R\"$ except $\"x=0\"$ ; you can't divide by zero and get a real number\r
\n" ); document.write( "\n" ); document.write( "the domain D is:( $\"-infinity\"$ , $\"0\"$ ) U :( $\"0\"$ , $\"infinity\"$ ) \r
\n" ); document.write( "\n" ); document.write( "and range is: $\"R-0\"$ \n" ); document.write( "
