| Summary: | This lesson focuses on finding the domain and range of relations. It moves into the definition of a function, functional notation and finding the inverse of functions.
After this lesson, you will be able to:
- tell the difference between a relation and a function.
- find the domain and range of a relation and function given the:
- ordered pairs
- graph
- relation
- identify functions given the ordered pairs, a graph and the function.
- use functional notation.
- find the inverse of a function given the ordered pairs, a graph and the function.
- use the vertical line test to determine if a graph represents a function.
