Q2 Define a relation R on the set N of natural numbers by is a natural number less than . Depict this relationship using roster form. Write down the domain and the range.
It is given that
is a natural number less than
As x is a natural number which is less than 4.
Therefore,
the relation in roaster form is,
As Domain of R = set of all first elements of the order pairs in the relation.
Therefore,
Domain of
Now,
Range of R = set of all second elements of the order pairs in the relation.
Therefore,
the range of
Therefore, domain and the range are respectively
