You can put this solution on YOUR website!
$\"y=3x%5E%28-2%29=3%2Fx%5E2\"$
\n" ); document.write( "So all values are allowed in the domain except $\"x%3C%3E0\"$ .
\n" ); document.write( "Since the denominator is a square, it's always positive.
\n" ); document.write( "So the entire function is always positive.
\n" ); document.write( "Asymptote as x approaches $\"infinity\"$ is $\"y=0\"$ .
\n" ); document.write( "So the range is ( $\"0\"$ , $\"infinity\"$ ).
\n" ); document.write( "
