Question

Witch of the following sets represents the domain of the function shown?

{(2,3), (4,7), (5,9), (11,6)}

Answer 1

The domain of the function is also known as all of the x values of the points of the function.

Since a function cannot have a repeated x value, all of the x values must be different.

So in the points given, the set that represents the domain is:

{2, 4, 5, 11}

Answer 2

So remember that domain is the list of possible x values in a relation.

In this case, our domain would be {2,4,5,11}.
