Part 1
Is this a​ function?
No
Yes
Your answer is correct.
Part 2
The domain is ​{

enter your response here​}.

Part 1: Since each input (the first number in each ordered pair) is associated with exactly one output (the second number), the relation is a function. You've confirmed that the answer is "Yes."

Part 2: 
The domain of a relation is the set of all possible inputs, or the first elements of each ordered pair. In this case, the domain is the set of the first numbers in the pairs: 

\[
\text{Domain} = \{3, 4, 8\}
\]

Part 3: The range of the relation is the set of all possible outputs, or the second elements of each ordered pair:

\[
\text{Range} = \{2, 3, 8\}
\]

4. How do you define the codomain of a function?
5. Can a relation with repeating outputs still be a function?

**Tip**: For a relation to be a function, each input must map to exactly one output.
