**Give the domain and range for the relation. Then determine whether the relation**

**is a function.**

{(3, 4), (4, 3), (0, 3), (−2, 4)}

**Answer:**

The domain of a function is a list of all of the possible inputs for the function. In this case the domain is {-2,0,3,4}

The range is the list of all possible outputs of a function, here this is {3,3,4,4}.

In order for this to be a function, you need to have exactly one output for every input. Since there are no repeated values in the domain, this relation is a function.
