The image provides an introduction to domain and range using simple examples and relations.

### Key Points:

1. **Understanding Relations**:
   - The example starts by defining relations using sentences like "Riku learned how to scuba dive." Here, "Riku" is related to "scuba dive" in the same way numbers can be related through mathematical operations.
   - The term on the left ("Riku") represents the **domain** (input), and the term on the right ("scuba dive") represents the **range** (output).

2. **Mathematical Representation**:
   - Relations can also be represented mathematically, such as:
     - "____ plus 2 equals ____"
     - "____ times \( \frac{1}{2} \) equals ____"
   - In this context, the number in the blank on the left is from the **domain** (input), and the result (output) is from the **range**.

3. **Domain and Range Example**:
   - For the operation "____ minus 11 equals ____," you are asked to identify which numbers belong to the **domain** or the **range**. The available numbers are: 12, 25, \( \frac{1}{2} \), 14, 9, \(-2\).

### Solution Strategy:
You need to:
- Drag numbers into the Domain and Range categories.
- The domain represents possible inputs (left-hand side of the relation), and the range represents the outputs (right-hand side of the relation).

### If you want to explore this topic more:
1. Would you like me to solve specific examples from this?
2. Should I explain domain and range in more detail?
3. Do you want more examples of how to apply this to mathematical functions?
4. Should I define how to determine the domain and range in a given relation?
5. Can I provide exercises for further practice on identifying domain and range?

**Tip**: The domain of a function consists of all possible input values (x-values), while the range consists of all possible output values (y-values).

Introduction to Domain and Range. Different words can be used to complete the sentence: _______ learned how to _______. The example 'Riku learned how to scuba dive' shows how to identify domain and range in both linguistic and mathematical contexts.

Explore how to determine the domain and range of mathematical relations through simple examples. This page introduces basic arithmetic operations such as addition and subtraction and helps students understand the inputs and outputs of relations, using both linguistic and mathematical approaches. Suitable for middle school students (Grades 6-8).
