To ensure Joe's table represents a function, each x value must uniquely correspond to a y value.

From the table:

x=−5 corresponds to y=4.

x=n currently corresponds to y=6.

x=6 corresponds to y=7.

x=−1 corresponds to y=2.

 

To ensure the function property, x=n must uniquely map to a y value that is not already used by another x value.

 

From the provided options:

−5 corresponds to&...
