(a) List the ordered pairs that belong to the relation.

My ANS: (a,a),(b,a)(b,b),(c,a),(c,b),(c,c),(d,a),(d,b)(d,d)

(b) Find the (boolean) matrix of the relation.

I did review another answer posted along the same question, but uses a different shape. I think my matrix is correct based on my pairs, but i'm concerned about the pairs.

Please see the attached.
Consider the following Hasse diagram of a partial ordering relation R on a set A:
(a) List the ordered pairs that belong to the relation. Keep in mind that a Hasse diagram is a graph of a partial ordering relation so it satisfies the three properties listed in number 5 part(b).
(b) Find the (Boo

Given S = {0, 1}, let R be the partial order relation on S X S X S such that for all ordered triples (a, b, c) and (d, e, f) in SXSXS (a, b, c) is related to (d, e, f) a =

Qu1) Is it true that ρ(AUB)= ρ(A) U ρ(B)? justify your answer.
Qu2) Consider the function f:A→A defined by f(x)=x+1 and justify your answers.
a) For A=ν (integers) is f onto?
b) For A=R(real number) is f injective?
c) For A=Q (rationals) is f onto?
d) For A=Z(all integers) is f a bijection?
Q3)
a) Let f : R→R

The Whodunit system design had a great start, and providing more detail is the next appropriate step in the design process. Collaboration diagrams help provide this additional detail, and they will be the focus of this assignment.
For this assignment, you will prepare a collaboration design and description in Microsoft Word
