y=-x^2+7\r
\n" ); document.write( "\n" ); document.write( "It is a parabola, degree 2
\n" ); document.write( "it is opening downwards x^2 is negative\r
\n" ); document.write( "\n" ); document.write( "x = -3, -1, 0, 1, 3\r
\n" ); document.write( "\n" ); document.write( "y=-x^2+7\r
\n" ); document.write( "\n" ); document.write( "x=-3 , y=-(-3)^2+7=>-2, (-3,-2)
\n" ); document.write( "x=-1, y= -(-1)^2+7=>=+6, (-1,6)
\n" ); document.write( "x=0, y= 7 , (0,7)
\n" ); document.write( "x=1, y= -(1)^2+7=> 6, (1,6)
\n" ); document.write( "x=3,y=-(3)^2+7=>-2, (3,-2)\r
