1. **State the problem:** Determine if the given mapping from Set A to Set B represents a function. 2. **Recall the definition of a function:** A function is a relation where each element in the domain (Set A) maps to exactly one element in the codomain (Set B). 3. **Analyze the mapping:** - Set A = \{2, 3, 4, -2\} - Set B = \{-4, 0, 9\} - Mappings: 2 \to -4, 3 \to 0, 4 \to 9, -2 \to 0 4. **Check if each element in Set A has exactly one arrow:** - 2 maps to -4 (one arrow) - 3 maps to 0 (one arrow) - 4 maps to 9 (one arrow) - -2 maps to 0 (one arrow) 5. **Conclusion:** Each element in Set A maps to exactly one element in Set B, so the mapping is a function. **Final answer:** The mapping diagram above **represents** a function since **each element in Set A maps to exactly one element in Set B** where there
