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.
Questions to think about 1. What do we see when we change the values of l and m? 2. What do we see when we change the value of a? 3. What is the difference when a is negative and when a is positive?
