Skills
- identify (functions given sets of ordered pairs) #dok1
- identify (functions given tables) #dok1

Learning Targets
- I can identify a function from a set of ordered pairs. #dok1
- I can identify a function by examining a table of values. #dok1
- I can identify a function using a mapping diagram. #dok1
- I can identify a function from its graph. #dok1
- I can analyze a representation to determine if it is a function by checking that each domain value corresponds to exactly one range value. #dok2
Big Ideas
- A function assigns to each input exactly one output, which can be represented in multiple ways.
- Identifying functions helps analyze and interpret relationships between variables in mathematics and real-world contexts.
Essential Questions
- What makes a relationship a function?
- How can you tell if a set of ordered pairs, table, mapping, or graph represents a function?
- Why is it important for each input to have only one output in a function?
- What are some real-life situations that can be represented using functions?
- How do different representations (tables, mappings, graphs) help us understand functions?
