    So you go down the table and make the equation y= x^2

    very good, now if we connect these points, then the line will be y=x^2

    well if y is greater then x^2, the y values in the the shaded region must be of greater values than the y=x^2 curve

    so shade the region above the curve

    some times it is good to choose a point and check it , say the point (0,1) which is above the curve, to check y>x^2 1>0^2 1>0 which is true, so the point is in the region

    the last thing to mention is that the line in not included in the region because we are doing y>x^2 if we were doing y≥x^2, the line would be included
