Let )=4x√−6x for x> 0. find the open intervals on which f is increasing (decreasing). then determine the x-coordinates of all relative maxima (minima).
1. f is increasing on the intervals
2. f is decreasing on the intervals
3. the relative maxima of f occur at x =
4. the relative minima of f occur at x =
notes: in the first two, your answer should either be a single interval, such as (0,1), a comma separated list of intervals, such as (-inf, 2), (3,4), or the word "none".
in the last two, your answer should be a comma separated list of x values or the word "none".
