Answer:

B: { (-3, 9), (-2, 4), (2, 4), (3, 9) }

Explanation:

This shows a function because, for each x value, there is not another x value of the same number

I hope this helped answer your question! Have a great rest of your day!

Answer 2

I’m going to say B because a c and d all repeat x which makes them not a function
