A hyperbola converging at x=-1 and y=0 at the other end could also serve as a monopolistic demand curve, but not a hyperbola converging at x=0 and y=0 where the corresponding marginal revenue will be always nil.

Equilibrium of output and price are achieved where marginal cost equals marginal revenue. This comment is by Peter L. Griffiths. Anonymousnoreply@blogger.com
