Determine the domain and the range of the relation, and tell whether the relation is a function. \( \{(11,6),(21,-2),(39,6),(11,1),(52,1)\} \)

To determine the domain, list the unique first elements from each ordered pair: • From (11,6), (21,-2), (39,6), (11,1), and (52,1), the x-values are 11, 21, 39, 11, and 52. • The unique set is {11, 21, 39, 52}. Next, to determine the range, list the unique second elements: • The y-values are 6, -2, 6, 1, and 1. • The unique set is {-2, 1, 6}. To decide if the relation is a function, check whether each input has exactly one output: • Notice that the input 11 appears twice with different outputs (6 and 1). • Because an input (11) corresponds to more than one output, the relation is not a function. Thus, the domain is {11, 21, 39, 52}, the range is {-2, 1, 6}, and the relation is not a function.
