Question Analysis
The question tests the student's ability to determine whether a given set of ordered pairs represents a function. A function requires that each input value (x-value) corresponds to exactly one output value (y-value).

Key Concept Explanation
A function is a special type of relation where each element in the domain (x-values) corresponds to exactly one element in the range (y-values). If any x-value has more than one y-value, then the relation is not a function.

Step-by-step Solution
1. List the given ordered pairs: {(7, 11), (8, 13), (9, 15)}.
2. Check for duplicate x-values: 7, 8, and 9 are all unique.
