(a) Find the intervals on which f is increasing or decreasing. (b) Find the local maximum and minimum values of f. (c) Find the intervals of concavity and the inflection points. 9. f(x) = x' - 3x? – 9x + 4 10. f(x) = 2x' - 9x? + 12x – 3 | 11. f(x) = x - 2.x² + 3 12. f(x) = x² + 1· 13. f(x) = sin x + cos x, 0
