Algebra.Com's Answer #16282 by longjonsilver(2297)![]() ![]() You can put this solution on YOUR website! well, centre is x=-1, y=2 and has radius =3\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "So, the x values vary from -4 to 2... 3 either side of -1 ( the centre) \n" ); document.write( "and the y values vary from -1 to 5... 3 either side of 2 ( the centre).\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Domain is -4 <= x <= 2 \n" ); document.write( "Range is -1 <= y <= 5\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Jon. \n" ); document.write( " \n" ); document.write( " |
