To determine which table does not represent a function, we need to identify if any x value in the table has multiple corresponding y values. A relation is not a function if any x value maps to more than one y value.

Let's analyze each table:

A. Here, x=−7 appears twice with different y values (63 and 17). This violates the definition of a function because x=−7 maps to both y=63 and y=17.

B. Each x value (-2, -4, -6, -8) has a unique y value. This represe...
