The curve is a parabola. Make a perfect square in terms of y. i.e . write y^2 + y as ( ( y + 1/2 ) ^ 2 ) - 1/4. The perfect square is made by managing the coefficient of the y term, you can add or replace a constant which will be taken care of later.
Now, the equation is (y + 0.5 ) ^2 = x - 0.25. If you know the general plot of the parabola y^2 = 4.a.x you can plot this by shifting the vertex of the parabola to ( 0.25 , -0.5 ).
Use the link below and input the equation to see the general plot of y^2=4ax(here, a is an arbitrary constant).
