set a
set b
answer attempt 1 out of 2
a function since

Explanation:

Step1: Recall function definition

A function is a mapping where each element in the domain (Set A) has exactly one corresponding element in the codomain (Set B).

Step2: Check each element in Set A

• Element 9 maps to -2 (one output)
• Element -1 maps to 7 (one output)
• Element -3 maps to -2 (one output)

All elements in Set A have exactly one output in Set B.

Answer:

This mapping is a function since every element in Set A is mapped to exactly one element in Set B.
