Using the two graphs below (one of f and the other off"), approximate the following. If not enough information is given to determine what is asked, explain why. y7f ( x) b, Critical points of fwhich cannot a. Critical points of f be classified by using the second c. Intervals on which f is increasing derivative .Assuming f and f' are polynomials, determine the degree of f Classify the critical points of f' as relative maxima or minima
