Both infimum and supremum exist.
Explanation of Solution
Given Information:
The given set is
The set that is given is
The given set is decreasing,
be 1 and the supremum will be 2.
Hence, both infimum and supremum exist.
(c)
To find: The supremum and infimum of the given set.
(c)
Answer to Problem 3E
Infimum exists and supremum doesn’t exist.
Explanation of Solution
Given Information:
The given set is
The set that is given is
Therefore, the set has no upper bound and the lower bound is 0. Therefore, the infimum will
be 0 and no supremum exists.
Hence, infimum exists and supremum doesn’t exist.
