Domain defines all possible values x can take.
\n" ); document.write( "In your case, you just don't want the expression inside the radical to be negative, that is:
\n" ); document.write( "3x+12 >= 0
\n" ); document.write( "3x >= -12
\n" ); document.write( "x >= -4
\n" ); document.write( ".
\n" ); document.write( "OR, domain is
\n" ); document.write( "[-4, +oo)
\n" ); document.write( "where oo represents infinity\r
\n" ); document.write( "\n" ); document.write( "
