These are guided notes for a lesson on determining if a relation is a function or not. Skills covered are: identifying a relation as a function from ordered pairs, tables, and graphs. Introduces the concept of writing and solving function notation.

The notes include key vocabulary, examples, and illustrations.

I have included a teacher key to show you what to fill in the blanks as your students follow along. I have also included specific things I said to make sure the students understood.

To use these notes, I simply projected them onto my whiteboard, gave the students their blank copies, and had them follow along and write what I wrote. This works great when you do not have loads of time, or students do not have the attention span, to take lengthy notes and it helps to still leave time for working independently!

I provide the Word version of these notes so that you may edit them to your liking but you could also save as a PDF and use an interactive board to annotate (I can send you a PDF if needed).

I have several others I am working on getting teacher keys for. Let me know if you're searching for a particular topic/lesson!
