4. Find f'(x) for f(x) = 3x+2 4x-5 6. Find the intervals of increasing, decreasing, and constant for f(x) = x-3x-9x + 12. 8. Determine the concavity of the function (concave up and concave down) and find points of inflection: f(x) = x44x. 10. Determine where the given function is increasing and where it is decreasing, where it's concave up and concave down, relative (local) extrema (Use Second Derivative Test), and points of inflection. Also, to complete the graph find the zeros of the function 2x4 - 8x3 f(x) = 11. Find the Vertical and Horizontal (Slant) Asymptotes for each function a) f(x) = x 15 X-5 5x b) f(x) = = 2x+1 c) f(x) x-6x+4 = x-2 Sad surive art iliw
