Answer

Conclude that the relation is not a function because one x-value has multiple y-values.

Steps

Step 1 ：Check for duplicate x-values in the relation.

Step 2 ：Find that the x-value -1 occurs twice with different y-values: (-1, 7) and (-1, 6).

Step 3 ：Conclude that the relation is not a function because one x-value has multiple y-values.
