Question

Domain Range
2 2
4 1
6 4
8 3
Is this a function

Answer 1

To determine if a set of ordered pairs represents a function, you need to check if each input (from the domain) is associated with exactly one output (from the range).

From your data:

- For the input **2**, the output is **2**.
- For the input **4**, the output is **1**.
- For the input **6**, the output is **4**.
- For the input **8**, the output is **3**.

Since each input value (2, 4, 6, and 8) corresponds to exactly one output value, this is indeed a function.

In conclusion, yes, the provided pairs represent a function.
