We can clearly see the graph of a parabola with the equation (y-l)^2 = 4a(x-m) in red color If we change the values of l, m and a using their corresponding slide bars we will see that position and shape of the parabola gets changed. Let us observe how the shape and position of the parabola changes with changing values of l, m and a.
Questions to think about 1. What do we observe when we change the values of l and m? 2. What do we observe when we change the value of a? 3. What happens when a is negative and when a is positive
