The domain is all real numbers, since there are NO restrictions (i.e., no denominators, no square roots!) in the equation.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "You really should see my explanation of this topic on my own website. Please go to \"www2.seminolestate.edu/rrapalje\".
