Answer:

  C. Yes, because every x-value corresponds to exactly one y-value.

Step-by-step explanation:

The list of x-values is {-1, 0, 2, 4, 7}. We note that no two are the same, so this is a functional relation.

The set of ordered pairs is a function because each x-value corresponds to exactly one y-value.
