To determine if a relation is a function, we need to check if each input (or "x" value) is associated with exactly one output (or "y" value).
Without the actual mapping diagram to reference, I can provide a general guideline:
- If any input (x) corresponds to more than one output (y), then the relation is not a function.
- If every input corresponds to exactly one output, then the relation is a function.
If you have access to the mapping diagram, check it to see if any x value points to multiple y values.
Based on the options you provided, you would choose:
- If any x is mapped to multiple y's: The relation is not a function.
- If every x is mapped to one y: The relation is a function.
Please evaluate the mapping diagram accordingly to make your selection.
