What does the supply curve of a pure monopolist form look like?

The supply curve of a pure monopolist is not well-defined like that of a competitive firm because a monopolist sets prices based on demand rather than producing a specific quantity at a given price. Instead of a typical upward-sloping supply curve, a monopolist determines the quantity to produce by equating marginal cost with marginal revenue, and then uses the demand curve to set the price. Consequently, the monopolist's pricing and output decisions are influenced by the market demand, leading to a downward-sloping demand curve rather than a distinct supply curve.
