Stage 1 – Desired Results
Established Goals:
This section aims to:
1. distinguish a function from a mere relation; and
2. find the domain and range of functions or relations
Understandings:
Students will understand… the definition of relation the definition of function the relationship between relation and function
Essential Questions:
Is the relation a function?
How do you define a relation?
What are the methods used to define a relation?
How can you identify the domain and range in a relation and function?
Students will know… the domain and range of a relation the domain and range in a function the methods used to define a relation
Students will be able to… construct tables, and equations to express functions translate information about functions given in a table, or an equation to one of the other form
