Question

Which of the following sets represents the domain of the function shown? {(2, 3), (4, 7), (5, 9), (11, 6)} {2, 4, 5, 11} {3, 7, 6, 9} {(3, 2), (7, 4), (9, 5), (6, 11)} {2, 3, 4, 5, 6, 7, 11}

Answer 1

We are given first set of relations:  {(2, 3), (4, 7), (5, 9), (11, 6)}.

We need to find the set for domain for the given relation.

Note: Domain of a relation are the first elements (values) of the given coordinates.

For the given coordinates, (2, 3), (4, 7), (5, 9), (11, 6), we have first values 2,4,5 and 11.

Therefore, Domain set is {2, 4, 5, 11}.
