Vedclass · Answer

(A) The relation $R$ is defined on the set of integers $Z$ as $R = \{(a, b) : a, b \in Z, a - b \in Z\}$.Since the difference between any two integers $a$ and $b$ is always an integer,every pair $(a, b)$ where $a, b \in Z$ satisfies the condition $a - b \in Z$.Therefore,$R = Z 	imes Z$.The domain of $R$ is the set of all first elements of the ordered pairs in $R$,which is $Z$.The range of $R$ is the set of all second elements of the ordered pairs in $R$,which is $Z$.Thus,the domain is $Z$ and the range is $Z$.

Let $R$ be the relation on $Z$ defined by $R = \{(a, b) : a, b \in Z, a - b \text{ is an integer}\}$. Find the domain and range of $R$.
