{ (-2, 4), (0, 2), (-1, 3), (4, -2) } The set of ordered pairs above: A mapping diagram has 2 boxes. Box 1 is labeled domain with entries negative 3, 4, negative 1, 5. Box 2 is labeled range with entries 3, 7, negative 2. Arrows show which domain value match onto which range value. An arrow goes from negative 3 to 3, 4 to 7, and arrows go from both negative 1 and 5 to negative 2. The mapping diagram above:
