Answer

Domain = (Arkansas, Texas, Oklahoma, Oregon) Range= $(4,32,5)$

Work Step by Step

The input takes the place of the x-value, so the domain is represented by every unique input value. Since all four states are included in the relation, they are all in the domain. Therefore the domain of this relation is (Arkansas, Texas, Oklahoma, Oregon) The range is the set of unique y-values in the relation. Although the values of $10$ and $8$ are shown in the output box, they are not at the end of an arrow. So, $4$, $32$, and $5$ represent the range of this relation, where $5$ is only included once despite being repeated. $(4,32,5)$
