From the given figure. we observe that 

P = {5,6,7}, Q = {3,4,5}

 And the relation in roaster form is ,  R = \left \{ {(5,3), (6,4), (7,5)} \right \}

As Domain of R = set of all first elements of the order pairs in the relation.
Therefore,
 Domain of  R = \left \{ {5, 6, 7} \right \}

Now,
Range of R = set of all second elements of the order pairs in the relation.
Therefore,
the range of    R = \left \{ {3, 4, 5} \right \}
