Exercise 5.7.2 Let f (9) = (2052(9) 2 Sinai). Find the intervals where f is increasing and the intervals where f is decreasing in [0, 221:]. Use this information to classify the critical points of f as either relative maximums, relative minimums, or neither. Exercise 5.7.4 Given the graph of a tnction f, determine the intervals where f is increasing, constant, and.' decreasing. (b) (d)
