Yes, it is a function. The domain is the set {-1,2,3}. The range is the set {5,6,7,8}

Answer 1

To determine if the data in the diagram represents a function, we need to check if each input (domain) has a unique output (range).

In the data provided:
- Each output (such as the numbers 2, 3, and -1) is associated with one or more inputs (the numbers 5, 6, 7, 8).
- However, the output 2 is associated with multiple inputs (5, 6, and 8), meaning that we have multiple inputs mapping to the same output.

This implies that the data does **not** meet the definition of a function (where each input must map to exactly one output).

Here’s the summary:

- **Not a function.**
- **Domain:** The set of all inputs (numbers corresponding to the first column) is {5, 6, 7, 8}.
- **Range:** The set of all outputs is {-1, 2, 3}.

So the correct response would be:
**Not, it is not a function. The domain is the set {5, 6, 7, 8}. The range is the set {-1, 2, 3}.**
