relation 2 relation 3 relat
{(9, u), (9, k), (9, s), (1, e)}
nding to each relation that represents a function.
relation 2 ✓ relation 3 relation 4

Explanation:

Step1: Recall function definition

A relation is a function if each input (first element of the ordered pair) has exactly one output (second element of the ordered pair).

Step2: Analyze Relation 3

For the relation \(\{(9, u), (9, k), (9, s), (1, e)\}\), the input \(9\) is paired with \(u\), \(k\), and \(s\) (multiple outputs). The input \(1\) is paired with \(e\) (one output). Since \(9\) has more than one output, this relation is not a function.

(Assuming the task was to determine if Relation 3 is a function, the analysis shows it's not. If the original question was different, adjust accordingly, but based on the visible text about "relation that represents a function", this is the analysis for Relation 3.)

Answer:

Relation 3 is not a function (because the input 9 is mapped to multiple outputs: u, k, s).
