This PowerPoint™ lesson teaches students from Algebra 2 to Precalculus about Functions. The lesson requires no extra work on the teacher's part. Display it via a projector or interactive board/tv, click through the slides which include animation and natural transitions, while walking around the room engaging with your students. This is also a great tool for asynchronous learning (easy to share with students to work through on their own time, and perfect for making videos).

The lesson includes examples that cover:

• the definition of a function (determining if a set is a function)
• evaluating functions (piecewise function included)
• the difference quotient (2 examples)
• domain of a function (interval notation)

This is a wonderful resource for those new to teaching, or new to the material. It gives a great visual representation to student.
