### range:
Explanation
## Step 1: Identifying the x-values### The domain of a relation is the set of all possible x-values (inputs). In this case, the x-values of the given ordered pairs are -7, 8, 0, -9, and 4.## Step 2: Identifying the y-values### The range of a relation is the set of all possible y-values (outputs). The y-values of the given ordered pairs are 6, -2, 2, 8, and 2. Since sets don't contain duplicate values, the range is -2, 2, 6, and 8.## Step 3: Writing the domain and range as sets### We write the domain and range as sets in ascending order. The domain is
. The range is
