Question #43467

Let f(x)=2-(2/x)+(6/x^2). 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 which intervals?

2. f is decreasing on which intervals?

3.the relative maxima of f occurs at x =?

4. the relative minima of f occurs 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".
