To find the domain of the relation G, we need to identify all the unique x-values in the ordered pairs. The domain is the set of all possible x-values.Looking at the ordered pairs in G, we have:(3,2), (-1,2), and (-8,-1).The x-values are 3, -1, and -8. Therefore, the domain of G is:domain = {3, -1, -8}To find the range of the relation G, we need to identify all the unique y-values in the ordered pairs. The range is the set of all possible y-values.Looking at the ordered pairs in G, we have:(3,2), (-1,2), and (-8,-1).The are, 2 Since 2 is repeated, we only include it once in the set. Therefore, the range of G is:range = {2, -1}
