If TR curve is parallel to X Axis then give the AR and MR curves???

It means that since TR curve is parallel to X axis Ed = 1

Hence the Demand Curve should be a rectangular Hyperbola

When TR curve is parallel to X- axis, then MR is zero. Therefore, MR curve is also a horizontal straight line and coincides with the output-axis.

When TR curve is parallel to X-axis, then the demand curve will be downward sloping.
