Algebra.Com's Answer #726244 by TeachMath(96) ![]() You can put this solution on YOUR website! You are DEFINITELY correct that the domain is NOT EQUAL to 4, or, it's all reals, EXCEPT 4.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "In INTERVAL NOTATION, this is: (- infinity, 4)U(4, infinity) \n" ); document.write( "PAY no attention to any answer that's different! \n" ); document.write( "The other person who said that x is not equal to 8 is WRONG, as usual. \n" ); document.write( " |
