The demand curve for a monopoly is:


1. the MR curve above the AVC curve.
2.above the MR curve.
3.the MR curve above the horizontal axis.
4. the entire MR curve.

The correct answer is option 3: the MR curve above the horizontal axis.

To understand why, we need to understand the concept of a monopoly and its demand curve. A monopoly is a market structure in which a single firm has control over the supply of a particular product or service. As a result, the firm can influence the price and quantity of the product in the market.

The demand curve for a monopoly represents the relationship between the price of the product and the quantity of the product that consumers are willing to purchase at that price. It shows the maximum price that consumers are willing to pay for different quantities of the product.

The marginal revenue (MR) curve for a monopoly represents the additional revenue that the firm receives from selling one additional unit of the product. Due to its market power, a monopoly can sell more units of the product by lowering its price. However, when the firm lowers the price, it will receive less revenue for each unit sold. Thus, the MR curve for a monopoly lies below the demand curve.

Option 3 states that the demand curve for a monopoly is the MR curve above the horizontal axis. This means that the MR curve intersects or lies above the horizontal axis, which represents zero price and quantity. The reasoning behind this is that a monopoly can only sell a certain quantity of the product at a positive price. If it were to sell at a zero price, it would not generate any revenue. Therefore, the MR curve for a monopoly is above the horizontal axis, indicating that the firm can still generate positive revenue by selling at a positive price.

In summary, the demand curve for a monopoly is represented by the MR curve above the horizontal axis because a monopoly can generate positive revenue by selling at a positive price.
