The domain of the following relation: r: {(-4, 3), (3, 6), (-2, 1), (3, 6)} is

Solution:

The domain is the set of all the input values of a function and range is the possible output given by the function.

The relation given is

r: {(-4, 3), (3, 6), (-2, 1), (3, 6)}

Here the domain is

dom (r): {-4, 3, -2, 3}

Therefore, the domain is {-4, 3, -2}.

Example:

The domain of the following relation: r: {(1, 2), (3, 4), (5, 6), (7, 8)} is

Solution:

The domain is the set of all the input values of a function and range is the possible output given by the function.

The relation given is

r: {(1, 2), (3, 4), (5, 6), (7, 8)}

Here the domain is

dom (r): {1, 3, 5, 7}

Therefore, the domain is {1, 3, 5, 7}.

Summary:

The domain of the relation r: {(-4, 3), (3, 6), (-2, 1), (3, 6)} is {-4, 3, -2}.
