Draw 3 graphs for a monopoly and a regulated natural monopoly showing these 3 things

1. The average fixed cost curve will never intersect with either the horizontal or vertical axis.
2. There must be proper positioning of the Average Total Cost curve and Average Variable Cost curve.
3. The Average Total Cost curve and Average Variable Cost curve must not touch (in between is average fixed costs - which can never be zero). Show the area of economic profit for a monopolist. Show where a natural monopolist prices.
