Question

fill in the blanks below in order to justify whether or not the mapping shown represents a function.

Explanation:

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

• The element 3 in Set A maps only to 1 in Set B.
• The element 6 in Set A maps only to -3 in Set B.
• The element 9 in Set A maps only to 2 in Set B.

Every element in Set A has one and only one output in Set B, so this meets the definition of a function.

Answer:

The mapping represents a function. Each element in Set A is mapped to exactly one element in Set B, which satisfies the definition of a function.
