Hint: The normal line is perpendicular to the tangent line. If two lines are perpendicular their slopes are negative reciprocals -- i.e. if the slope of the first line is mm then the slope of the second line is −1/m
Here the given curve is f(x)= (-1)+2x^2, we have to find the point when the normal to the curve f(x) at the point (1, 1) interests second time to the parabola
