$\"l%28x%29=+3%2F%28x%5E2%2B7%29\"$
\n" ); document.write( "The domain is the values of x where l(x) is defined.
\n" ); document.write( "The only issue is if the denominator equals zero since division by zero is undefined.
\n" ); document.write( "Since the denominator contains a square of x, it will always be greater than zero.
\n" ); document.write( "Therefore the domain is all x from ( $\"-infinity\"$ , $\"infinity\"$ ). \n" ); document.write( "
