Answer: Distinguish between Perfectly elastic demand and Perfectly inelastic demand

|---|---|---|
| Meaning | A very small (or no) change in price causes an infinite change in quantity demanded. | Quantity demanded does not change at all whatever the change in price. |
| Coefficient | \(E_d = \infty\) | \(E_d = 0\) |
| Demand curve | Horizontal straight line parallel to the X-axis. | Vertical straight line parallel to the Y-axis. |
