Consider two issues for domain:

\n" ); document.write( "1. The denominator isn't 0

\n" ); document.write( "2. What's under an even root (usually 2...i.e. square root) isn't negative.

\n" ); document.write( "If this is $\"sqrt%2823-x%29\"$ then 23-x >= 0 so -x >= -23 so x <= 23.

\n" ); document.write( "The domain is all real numbers such that x<=23. \n" ); document.write( "

\n" );
