Answer 1

To determine which mapping diagram represents a function, we need to check if each input (x-value) is associated with exactly one output (y-value).

Here are the criteria for identifying a function:

• Each element in the domain (x-values) must map to one, and only one, element in the co-domain (y-values).

If you provide the specific mapping diagrams A, B, C, and D, I can help you analyze them to find out which one represents a function based on the criteria mentioned.
