Question

If $A=\{2,4,6,\}$, $B=\{5,7,1,9\}$.

Let R be the relation ‘is less than’ from A to B. Find Domain (R) and Range (R).

Answer 1

Under this relation $\left(R\right)$, we have

$R=(4,5);(4,7);(4,9);(6,7);(6,9),(8,9)(2,5)(2,7)(2,9)$

Therefore, Domain $\left(R\right)$ = $\{2,4,6,8\}$ and Range $\left(R\right)$ =$\{1,5,7,9\}$
