Determine the intervals on which f is increasing or decreasing. assuming that given gure is the graph of f'. Only consider the portion of the graph on the interval (0, 6). y (Give your answers as intervals in the form (at, ac). Use the symbol on for innity. U for combining intervals. and an appropriate III N type of parenthesis "(",") . [","]" depending on whether the interval is open or closed. Enter 6 if the interval is empty. Express numbers in exact form. Use symbolic notation and fractions where needed.) f is decreasing on Two days after he bought a speedometer for his bicycle. Lance brought it back to the Yellow Jersey Bike Shop. \"There is a problem with this speedometer,\" Lance complained to the clerk. \"Yesterday I cycled the 22mile Rogadzo Road Trail in 7'] minutes. and not once did the speedometer read above 15 miles per hour!\" \"Yeah?\" responded the clerk. \"What's the problem?" To explain Lance's complaint. rst compute his average velocity. (Use decimal notation. Give your answer to two decimal places.) average velocity: mileslour How did Lance use the Mean Value Theorem to explain his complaint? 0 As Lance's average speed is greater than 15 milesi'hour, at any moment of time the speedometer should show the speed that is above 15 milesfhour. O For 50% of time, Lance's speed exceeds his average speed that in turn is above 15 milesfhour. C) There is at least one moment of time when Lance's speed is equal to his average speed. At that moment Lance's speed exceeds the speed of 15 milesfhour
