Answer:
the table
Step-by-step explanation:
Any mapping (graph, table, diagram, or ordered pairs) in which the same x-value gives two or more y-values (range values) is NOT a function.
In the diagram, -2 gives two outputs; in the ordered pairs, 6 gives two outputs. Neither the diagram nor the set of ordered pairs represents a function.
The table has unique values in the x-column, so it is a function.
