=+b. Suppose that the patented technology is sufficiently advanced such that, for any set of input prices, there always exists an output level x at which it is (long-run) cost effective to switch to this technology. On a graph with output x on the horizontal and dollars on the vertical, illustrate two cost curves corresponding to the two technologies and then locate x. Then illustrate the cost curve that takes into account that a firm will switch to the patented technology at x.
