3. On the interval [-10, -5]: The maximum value is 9. The minimum value is –9. -10 and –6 are zeroes of the function. The function is increasing on (-10, -7) The function is decreasing on (-7, -5)

4. On the interval (-10, 10): An absolute maximum occurs at x = -7 An absolute minimum occurs at x = -5 A relative maximum occurs at x = 2. A relative minimum occurs at x = 4 A relative maximum occurs at x = 6 A relative minimum occurs at x = 9

5. AVERAGE RATE OF CHANGE OF A FUNCTION If a function is defined on the closed interval [a, b], the average rate of change of the function on the interval [a, b] is: On the interval [-3, 0], the average rate of change is: On the interval [1, 2], the average rate of change is:

6. On the interval [-3, 4], the average rate of change is: On the interval [6, 9], the average rate of change is:
