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.
 2. Check to see if your equation works by checking the check box.
 3. If you did Cartesian form, try it in parametric form or vice versa. 
 4. Try transforming the parabola by moving sliders 'h' and 'k' and adjust your equation(s).
 5. Reset the problem to try another.
