What is the domain of the function in this table

Option A:

{3, 4, 5, 6}

Solution:

In the given table X column have 3, 4, 5, 6 and Y column have 4, 4, 2, 5.

The domain is the set of all values for which the function is defined.

The domain of the function is set of all X values.

Option A: {3, 4, 5, 6}

Set of all X values {3, 4, 5, 6}.

It is correct.

Option B: (3, 4), (4, 4), (5, 2), (6, 5)

Here, the given values are ordered pairs of domain and co-domain.

It is not correct.

Option C: (3, 4)

Here, (3, 4) is a ordered pair of domain and co-domain.

It is not correct.

Option D: {2, 4, 5}

Here, {2, 4, 5} are values of co-domain.

It is not correct.

Hence {3, 4, 5, 6} is the domain of the function.

the answer is 24
