Let R = {(x, x + 5): x ϵ {9, 1, 2, 3, 4, 5}}.

Question:

Let $R=\{(x, x+5): x \in\{9,1,2,3,4,5\}\}$

(i) Write $R$ in roster form.

(ii) Find dom (R) and range (R).

 

Solution:

Given: $R=\{(x, x+5): x \in\{9,1,2,3,4,5\}\}$

(i) R is Foster Form is,

R = {(9, 14), (1, 6), (2, 7), (3, 8), (4, 9), (5, 10)}

(ii) Dom(R) = {1, 2, 3, 4, 5, 9}

Range(R) = {6, 7, 8, 9, 10, 14}
