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.
