A mapping diagram has two boxes. Box 1 is labeled domain with entries negative 3, 5, 3, negative 5. Box 2 is labeled range with entries 6, negative 2, 1. Arrows show which domain values map onto each range value. Negative 3 is mapped onto 6, 5 is mapped onto 6, 3 is mapped onto negative 2, and negative 5 is mapped onto 1. The above is
