Question

Dertermine whether the data diagram represents a functiona relastionship, and state the domain and range.1point)

Answer 1

To determine whether a data diagram (like a set of points or a graph) represents a functional relationship, you can apply the vertical line test: if any vertical line crosses the graph more than once, then the relationship is not a function.

To provide you with a more specific answer regarding the domain and range, I would need details about the data points or the diagram you are referring to.

### General Steps to Determine Functionality, Domain, and Range:

1. **Functionality**:
- **Vertical Line Test**: Check if any vertical line intersects the diagram at more than one point. If it does, the relation is not a function.

2. **Domain**:
- List all possible input values (usually the x-values). This can include all x-values represented in the diagram.

3. **Range**:
- List all possible output values (usually the y-values). This can include all y-values represented in the diagram.

If you can describe the diagram or provide specific data points, I can help analyze it further!
