Question

In the given figure find the domain, co-domain and range.

Solution

Correct option is

f = {1, 2, 3, 4}

From given figure we conclude that     

A → Domain of f = {p, q, r, s}

B → Co-domain of f = {1, 2, 3, 4, 5}

Range of f = {1, 2, 3, 4}

We should always remember “the range is subset of co-domain”.
