Hi,

I was wondering if I am doing this correctly. The question asks to state the maximum value, minimum value, least upper bound, and greatest lower bound of a bunch of given sets.

The question I am asking for is this one. {x : x E (0, 1)}

I am a bit confused. Therefore, is the following correct?


Maximum value: 0.9
Minimum value 0.1
Least Upper Bound: I'm not sure
Greatest Lower Bound: Not sure too.

For the least upper bound and greatest lower bound, how do I prove that IT IS the least upper bound and greatest lower bound?

Thanks in advance. Sorry for the stupid question. I'm slowly getting a hang of University math...
