find the domain and range of the relation and state whether or not the relation is a function.

{(1,3), 2,3), (3,3), (4,3)}

To find the domain and range of a relation, we need to identify the set of all input values (domain) and the set of all output values (range).

Looking at the given relation: {(1,3), (2,3), (3,3), (4,3)}

The first coordinate in each pair represents the input values (x-values), and the second coordinate represents the output values (y-values).

Domain:
The domain is the set of all possible input values. In this case, the x-values are 1, 2, 3, and 4. Therefore, the domain is {1, 2, 3, 4}.

Range:
The range is the set of all possible output values. In this case, the y-values are all 3. Therefore, the range is {3}.

Function or Not?
A relation is considered a function if each input (x-value) corresponds to exactly one output (y-value). In this case, all the x-values (1, 2, 3, 4) correspond to the same y-value (3). So, this relation is a function.

In summary:
Domain: {1, 2, 3, 4}
Range: {3}
Relation: Function
