a) find the intervals on which f is increasing or decreasing.
Is it ....f is decreasing on the intervals (- infinity, -1) and (1, infinity)...f is increasing on the interval (-1, 1).......
b)find the local min and max values of f..
For f(-1) I got undefined...
f(1)=1/4.......
What is the max? Min?
c) find the intervals of concavity and the inflection points.
