Hi!
No, this is not a function. To be a function, each value of x should be associated with one and only one value of y. However, here, we have many values of y for one value of x.
For exemple, at x=0, we have y=2 AND y=-2.
At x=5, we have many values of y.
Therefore, this is a relation, not a function. You can find more exemples here : Algebra - Relations and Functions | Secondaire | Alloprof
I hope I was able to help you! Feel free to ask us more questions if you have any!
