1. Let \(A =\{3,4,7,8\}\) and \(B = \{1,7,10\}\). Which of the following sets are relations from \(A\) to \(B\)?

(i) \(R_1 = \{(3,7), (4,7), (7,10), (8,1)\}\)

(ii) \(R_2 = \{(3,1), (4,12)\}\)

(iii) \(R_3 = \{(3,7), (4,10), (7,7), (7,8), (8,11), (8,7), (8,10)\}\)

2. The arrow diagram shows a relationship between the sets \(P\) and \(Q\).

Write the relation in

(i) Set builder form

(ii) Roster form

(iii) What is the domain and range of \(R\).

Answer:

(i) Set builder form of \(R =\)

\{(i, i) | i = i - i, i \in P, i \in Q\}

(ii) Roster form of \(R =\)

\{(i, i), (i, i), (i, i)\}

(iii) The domain of \(R =\)

\{i, i, i\}

and the range of \(R =\)

\{i, i, i\}
