It looks like you have uploaded an image of a question about identifying components of a function using an arrow diagram. However, the arrow diagram itself isn't visible in the image. To help you accurately, I would need a clearer view of the diagram or any additional context about how the elements are related.

Would you be able to describe the diagram or provide more details about the function, such as how the elements from set X and set Y are mapped in the diagram?

Let me know if you'd like further assistance!
