Skills
- decide (whether a relation is a function using verbal, tabular, graphical, and symbolic representations) #dok2
- analyze (relations represented in different formats) #dok2

Learning Targets
- I can identify functions from tables, graphs, verbal, and symbolic representations. #dok1
- I can analyze different representations to determine if they define a function. #dok2
- I can decide if a relation is a function based on its representation. #dok2
- I can compare relations to determine which, if any, are functions. #dok2
Big Ideas
- A function is a special type of relation where each input corresponds to exactly one output.
- Relations can be represented in many ways, and the structure of the representation determines whether it is a function.
Essential Questions
- What makes a relation a function?
- How can you tell if a relation represented as a table, graph, or equation is a function?
- Why does each input in a function correspond to only one output?
- How do different representations help you decide whether a relation is a function?
- What are some examples of relations that are not functions, and why?
