(1 point) Let f (x) = 2'5: x 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"
