###### Question:

3. Let S = {1,2,...,7,8) be ordered as in figure below. Consider the subset A = {3,6,7} of S. a. Find the set of upper bounds of A b. Find the set of lower bounds of A C. Does sup(A) exist? d. Does inffA) exist? 4. Repeat problem 3 for the subset B = {1,2,4,7) of S. 5. Let S be the ordered set in figure below. Suppose A = {1,2,3,4,5) is order-isomorphic to S and the following is a similarity mapping from Sonto A : f = {(2,1),(6,4),(c,5),(d, 2), (,3)} Draw the Hasse diagram of A.
