Algebra.Com's Answer #560065 by KMST(5347) You can put this solution on YOUR website! (-infinity,2) is \n" ); document.write( "from -infinity (considered not included because -infinity is not really a number \n" ); document.write( "to 2, with 2 not included. \n" ); document.write( "That is all real numbers x, such that x<2. \n" ); document.write( "That is the answer in interval form. \n" ); document.write( "You do not want (-infinity,2], because that includes x=2 (that is what the square bracket next to the 2 means. \n" ); document.write( "The other answers include numbers like x=5 that are not less than 2. \n" ); document.write( " |
