Big Ideas
- A function is a relationship where each input has exactly one output, which can be represented using ordered pairs or mappings.
- Recognizing functions from sets of ordered pairs and mappings helps in understanding and working with mathematical relationships.
Essential Questions
- What makes a relationship a function?
- How can you tell if a set of ordered pairs represents a function?
- What is a mapping and how does it show a function?
- Why is it important to be able to identify functions in different representations?
