or point of infection? Suppose the derivative of the function y-rx is y -(x-1 (x-3). At what points, if any does the graph of f have a local minimum, local maximu At what points, if any, does the graph of f have a local minimum? 0 A. The graph has a local minimum at x= O B. The graph has no local minimum. At what points, if any, does the graph of fhave a local maximum? O A. The graph has a local maximum at x O B. The graph has no local maximum. At what points, if any, does the graph of fhave a point of inflection? OA. The graph has a point of inflection at x O B. The graph has no point of inflection.
