7. Given f (x) = -x' - x2 - 3x + 2. f'(x) = 8. Use your calculator to graph f (x) and f'(x) in the following window: x: [-7.9, 7.9], y : [-10, 10]. Sketch below. 9. The relative maximum and minimum values of f (x ) occur at x = 10. f' (x) = 0 or f'(x) is undefined at x = 11. f (x) is increasing on what interval(s)? 12. f' (x) is positive on what interval(s)? 13. f (x) is decreasing on what interval(s)? 14. f' (x) is negative on what interval(s)
