To determine whether the relation is a function based on a mapping diagram, we need to check if each input (often referred to as "x" in function notation) is associated with exactly one output (or "y").
If there are any inputs that correspond to multiple outputs, then the relation is not a function. Conversely, if every input is connected to only one output, then the relation is a function.
Without seeing the specific mapping diagram you mentioned, I can't definitively state which option is accurate. Please refer to the mapping diagram and look for any inputs that have multiple outputs to make your determination.
- If you see inputs with a single output, choose Option #1: The relation is a function.
- If you see any inputs with more than one output, choose Option #2: The relation is not a function.
