You can put this solution on YOUR website!
No it is not because x = 0.3 is mapped to BOTH y = 0.6 AND y = 0.7 at the same time.

The rule with function is that any input needs to have EXACTLY ONE output.

So again, this relation is not a function.

Let me know if you need more help or if you need me to explain a step in more detail.
