Algebra.Com's Answer #316696 by robertb(5830)![]() ![]() You can put this solution on YOUR website! If y = 2x + 3, then solve the inequality x(2x + 3) <0.\r \n" ); document.write( "\n" ); document.write( "The critical numbers are 0, -1.5. \n" ); document.write( "For x < -1.5, x(2x + 3) > 0. \n" ); document.write( "For -1.5 < x < 0, x(2x + 3) < 0. \n" ); document.write( "For x > 0, x(2x + 3) > 0. \n" ); document.write( "Therefore the range of x is the interval(-1.5, 0). \n" ); document.write( " |
