Parabola: Parallel to the x-axis

1. Find the equation of the parabola in either standard form or parametric form based on the information displayed on the graph.
[br]2. Check to see if your equation works by checking the check box.
[br]3. If you did Cartesian form, try it in parametric form or vice versa. 
[br]4. Try transforming the parabola by moving sliders 'h' and 'k' and adjust your equation(s).
[br]5. Reset the problem to try another.
