Is a bounded set synonymous to a set that goes to infinity? I feel like unless a set is(adsbygoogle = window.adsbygoogle || []).push({});

(-infinity, n) or [n, infinity) it is not going to be unbounded.

The other thing that I was wondering is can a set be neither open nor closed AND unbounded? Doesn't the definition of open/closed imply that there is a boundary?

Thanks!
