To determine which set of points is not a function, we need to check each set of points to see if any input (x-value) maps to more than one output (y-value). A set of points is not a function if any input is repeated with different outputs.

Option A

Each input 9, 6, -8, -6, 7 and -7 maps to exactly one output.

This set is a function because no input is repeated with different outputs.

Option B

Each input -6, -3, 0, 3 and 7 maps to exactly one output.
