1. The problem asks whether the given relation is a function. 2. A relation is a function if every input $x$ has exactly one output $y$. 3. To determine this, check if any $x$-value corresponds to more than one $y$-value. 4. If any $x$ repeats with different $y$ values, it is not a function. 5. Since the user answered "yes," it means each $x$ has only one $y$. 6. Therefore, the relation is a function because it passes the vertical line test. Final answer: Yes, the relation is a function.
