Finding the Inverse of a Function Foldable
This finding the inverse of a function foldable was inspired by @druinok’s post from February
Last year, my Algebra 2 students really struggled with the concept of an inverse. So, this year, I decided to start talking about inverses very early in the school year. This will allow us to revisit the concept over and over as we explore different types of function in a much more in depth manner. By the time the EOI rolls around, my students should no longer be scared when they see the word inverse!
I want my students to be able to find the inverse if they are given a set of points, a graph, or an equation. Since we have only just started exploring functions in general, the examples we went through were quite simplistic. We will explore much more complicated inverses as the year progresses!
A lot of my students were terrified when I told them that we would be learning about inverses. By the end of the lesson, they were amazed that inverses were actually quite easy.

I am a math teacher in Philadelphia, PA. I use foldables in my classroom, but not as often as I would like to. I plan to use an interactive notebook next year for my advance math classes (Precalculus, IB Math Studies, etc.) I thank you greatly for the examples you posted on functions and their graphs. Keep up the great work! Perhaps you could do a webinar on your teaching ideas.
Is there an answer key for the domain and range activity. I am not very experienced with interval notation and want to make sure I have them correct.
I made an answer key last year, but I'm afraid it's long gone. This is what happens when I write answer keys on notebook paper and file them away in random places in my classroom… Sorry!
This might be a little too forward but I'm pretty sure I LOVE YOU! Thanks for all you do and share! Got any recommendations on Domain and Range notes for Algebra 1? camfan54@att.net or lrichardson@ccisd.net
Thanks!
Do you have on your website a copy of the domain and range card you used in the foldable?
Do you provide your students with all the colored construction paper? That must cost you a lot!
It does cost a bit. But, colors are pretty and so worth it.
Thanks for the sharing. These are excellent.
Thank you for all the wonderful resources!!!
The embedded files are not working anymore. I don't know if there was a flash player update that made them incompatible, but is there anyway I could get the files please? I was planning on using some of these with my Algebra I class.
Sarah, did you have students just identify the increasing and decreasing intervals or actually write them in interval notation? Any reason you didn't do positive and negative intervals?
We wrote the increasing and decreasing intervals in interval notation, too. My students REALLY struggled with it, though. I don't do positive and negative intervals because they're not in the OK standards. Otherwise, I'd do those at the same time.
Hi! I love the domain and range foldable. Do you have a copy of the practice cards they used? I didn't see it in the files, but I would love to use this resource in my class!
Hi! I love this idea. I have looked over the blogpost over and over, but I do not see the download for the cards you used. I downloaded an item that says "Word document of the cards", but that document doesn't look anything like yours. Is there a way you could send me the cards? You can email me at mbsawyer08gmail.com . Thanks for all of your great ideas!!
thanks for all the ideas. Do you have the answer key for the domain/range card sort? Can I get a copy?
Hi Sarah,
I am always so inspired by you! Thanks for all the great ideas. I think I've improved on your domain/range interactive cards at least from a cutting perspective. See http://systry.com/domain-and-range-cards/ for more information.
I absolutely LOVE everything on this page! I am definitely going to use all of it. Thanks so much for sharing! I'm starting my second year of teaching and I love finding amazing resources like this. You are amazing!
I used the Domain and Range foldable last year and LOVED IT! However, now I'm having trouble finding the copy of the graphs that fit into the middle of the interactive foldable. I looked on the website that you have linked above where you said you got them, but I can't find them! HELP!!!
