Question “8,14 please 8. The graph of the first derivative f’ of a function f is shown….”
8. The graph of the first derivative f’ of a function f is shown. (a) On what intervals is f increasing? Explain. (b) At what values of x does f have a local maximum or minimum? Explain. (c) On what intervals is f concave upward or concave down- ward? Explain (d) What are the x-coordinates of the inflection points of f? Why? y = f'(x) 2 6 8 9-18 (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 – 3×2 – 4x + 4 10. f(x) = 2x’ – 9×2 + 12x – 3 11. f(x) = x* – 2x² + 3 12. f(x) = r+ 1 13. f(x) = sin x + cos x, 0<x< 2T 14. f(x) = cos²x – 2 sin x, 0<x< 27 15. f(x) = (2x + e* 16. f(x) = x? In x 17. f(x) = x – x – Inx 18. f(x) = x*e* X
