You can put this solution on YOUR website!
If the range (the y-values) is (3,4,5,6,7,8), then the domain or x-values will be the squares of those numbers...
\n" ); document.write( "Since \"y+=+sqrt%28x%29\", then
\n" ); document.write( "\"y%5E2+=+x\"
\n" ); document.write( "and
\n" ); document.write( "the domain becomes (9,16,25,36,49,64)
\n" ); document.write( "
\n" );
