Hi I need help with this 4 questions:

1.

lff'(x) > 0 for all x on an interval I, then f O is increasing on | O has a local maximum on | O is decreasing on | O has a local minimum on | Below is the graph of the DERIVATIVE of f(x): On which of the following intervals is f(x) DECREASING (select all that apply). On which of the following intervals is f(x) DECREASING (select all that apply). Remember: The graph given in the image is the graph of f'(x)... it is NOT the graph of f(x). f'N (0,2) g f'N (2,3) g f'\\ (3,4) g f'\\ (45) g f'\\ (56) g f'\\ (6,8) g Let f(x) = 6x4 + 2x3. Select all intervals where f(x) is INCREASING, O (0, 00) O ( , 0) O ( - 0o , 3 4 )The graph of a function f (x) is given below: Select all points which are absolute extrema. 7.5 15 F Select all points which are absolute extrema.
