I can’t tell from your message because the relation itself isn’t shown. Give the relation (ordered pairs, mapping diagram, graph, or equation) and I’ll check.

Rules to decide:
- A relation is a function if every input (each x/domain value) is paired with exactly one output (one y).
- For a set of ordered pairs: no x-value may appear in two pairs with different y-values.
- For a graph: use the vertical line test (no vertical line intersects the graph more than once).
- For a mapping diagram: each domain element must have exactly one arrow leaving it.

If you paste the relation here I’ll tell you whether it’s a function and why.
