The table that does NOT represent a function is:
x y
-2 -2
-1 -2
0 -2
Because for the same input value of x, we have different output values of y (-2 and -2).

To determine which table does NOT represent a function, we need to check if there are any repeated x-values with different y-values in each table.
Let's go through each table and check:
Table 1:
x: -2, -2, -1
y: 2, -2, 1
In this table, the x-value -2 is associated with two different y-values (2 and -2). This means that it does not represent a function.
Table 2:
x: -1, 0, 2
y: 1, 0, -2
In this table, each x-value is associated with a unique y-value. This means that it represents a function.
Table 3:
x: -1, 1, 2
y: -1, 1, 2
In this table, each x-value is also associated with a unique y-value. This means that it represents a function.
Table 4:
x: -2, -1, 0
y: -2, -2, -2
In this table, each x-value is associated with the same y-value (-2). This means that it represents a function.
Based on the analysis, Table 1 does NOT represent a function as it has repeated x-values with different y-values.
