The domain of the relation is the set of all input values. In this case, the input values given are 3. So, the domain is {3}.
The range of the relation is the set of all output values. In this case, the output values given are 6, -6, 9, and 62. So, the range is {6, -6, 9, 62}.
To determine if the relation is a function, we need to check if each input has exactly one corresponding output. In this case, each input (which is 3) has multiple corresponding outputs (which are 6, -6, 9, and 62). Therefore, the relation is not a function.
