Question Analysis
The question tests the understanding of the definition of a function using a mapping diagram. A relation is a function if each input value (domain) points to only one output value (range).

Key Concept Explanation
A function requires that each input value (x-value) corresponds to only one output value (y-value). Multiple input values can correspond to the same output value.

Step-by-step Solution
1. List the given inputs and outputs: Inputs {5, 7, 9, 11} and Outputs {10, 22, 10, 14}.
2. Check if each input value points to exactly one output value.
