equation of parabola (x-l)^2 = 4a(y-m).
We can clearly see the graph of a parabola with the equation (x-l)^2 = 4a(y-m) in red color. If we change the values of l, m and a using their corresponding slide bars we will see that the position and shape of the parabola changes. Let us observe how the shape and position of the parabola changes as we change the values of l, m and a.
