Previous Problem List Next (1 point) Let f(z) Find the open intervals on which f is increasing (decreasing). Then determine the r-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 a = 4. The relative minima of f occur at a = 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 a values or the word none" Note: You can earn partial credit on this
