y=x^2-1 and x+y=1\r
\n" ); document.write( "\n" ); document.write( "y=x^2-1 \r
\n" ); document.write( "\n" ); document.write( "this is a parabola
\n" ); document.write( "generate values of x& y\r
\n" ); document.write( "\n" ); document.write( "x=0, y=-1 (0,-1)
\n" ); document.write( "y=0,x=1 (1,0)
\n" ); document.write( "x=-2, y=3 (-2,3)
\n" ); document.write( "x=2,y=3 (2,3)\r
\n" ); document.write( "\n" ); document.write( "and x+y=1\r
\n" ); document.write( "\n" ); document.write( "x=0,y=1 (0,1)
\n" ); document.write( "y=0,x=1(1,0)\r
\n" ); document.write( "\n" ); document.write( "Plot the points draw the curve and the straight line \r
\n" ); document.write( "\n" ); document.write( "\r
\n" ); document.write( "\n" ); document.write( "The solutions are (1,0) , (-2,3)\r
