Question

Let A = {1, 3, 5, 7} and B = {2, 4, 6, 8}. Let R = {(x, y), : x ϵ A, y ϵ B and x > y}. (i) Write R in roster form. (ii) Find dom (R) and range (R). (iii) Depict R by an arrow diagram.

Philoid · Accepted Answer

Given: A = {1, 3, 5, 7} and B = {2, 4, 6, 8}

(i) R = {(x, y), : x ϵ A, y ϵ B and x > y}

So, R in Roster Form,

R = {(3, 2), (5, 2), (5, 4), (7, 2), (7, 4), (7, 6)}

(ii) Dom(R) = {3, 5, 7}

Range(R) = {2, 4, 6}

(iii)
