Here is the problem:
absolute value of (2 + 1/x) > 1
I can solve this by finding the critical points 0, (x cannot = 0), -1 and - 1/3 (these by solving the problem as an equality). After finding the critical points I tested a point in each interval to determine the correct intervals. I understand this.
I am having trouble solving this problem using cases.
Any ideas? I can't seem to get the same answers when I try to use cases. I tried x > 0 and x < 0 etc.
Thanks for any help you can give.[/list]
