Let f(x)=2x^3â1. 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=none 3. The relative maxima of f occur at x =none 4. The relative minima of f occur at x =none
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".
