    Problem with intervals

    If S \subseteq R is a nonempty bounded set, and I_s := [inf S, sup S], show that S \subseteq I_s. Moreover, if J is any closed bounded interval containing S, show that I_s \subseteq J.

    Thanks for any help.

    With over forty postings you should understand that this is not a homework service nor is it a tutorial service.
    PLease either post some of your own work on this problem or at the very least, explain what you do not understand about the question.
