Hi y'all I was just wondering if anyone could help me out with some examples of the following:
a function f where two of the following conditions hold:
--f is continuous on [a,b],
--the interval [a,b] is closed,
--the interval [a,b] is bounded,
yet f is not bounded on [a,b].
a function f where two of the previous conditions hold and f IS bounded on [a,b].
a function f where with closed and bounded which does not attain its maximum value in D.
Thanks in advance for any help!
