Question Analysis
The question tests the understanding of the definition of a function using a mapping diagram. A relation is not a function if any input value (domain) points to more than one output value (range).

Key Concept Explanation
A function requires that each input value (x-value) corresponds to only one output value (y-value). If an input value points to multiple outputs, the relation is not a function.

Step-by-step Solution
1. List the given inputs and outputs: Inputs {3, 5, 7} and Outputs {6, 8, 10}.
2. Check if each input value points to exactly one output value.
