Question

The figure shows a relationship between the sets P and Q. Write this relation roster form. What is its domain and range?

✓

Answer

From the figure, the relation in roaster form is, R = {(5, 3), (6, 4), (7, 5)}
As Domain of R = set of all first elements of the order pairs in the relation.
$\Rightarrow$ Domain of R = {5, 6, 7}
Range of R = set of all second elements of the order pairs in the relation.
$\Rightarrow$ range of R = {3, 4, 5}.
