\n" );
document.write( "i don't know where to start, do i factorise the equation?
\n" );
document.write( "if i do factorise it i will get (x-1.5)(x-4) where do i go from that? :S

Pick values for x and sub them to find y. Plot the points and connect them with a smooth curve. \n" ); document.write( "---------- \n" ); document.write( "x...y \n" ); document.write( "----- \n" ); document.write( "0 12 (0,12) \n" ); document.write( "1 3 (1,3) \n" ); document.write( "2 -2 (2,-2) \n" ); document.write( "--------- \n" ); document.write( "You can use Excel to make the table, and then the graph. \n" ); document.write( "Or, you can DL FREE software from \n" ); document.write( "http://www.padowan.dk.com \n" ); document.write( " |
