Are you looking for a fun and engaging way to have your students practice finding an inverse for a function? This paper chain activity is exactly what you need!In this scavenger hunt style activity, students will create a paper chain. Students will practice finding the inverse of functions. This activity includes linear, powers, radicals, and rational functions. Students will answer a total of 16 questions.How does the paper chain activity work?This activity has 16 problems.Students start on Strip A that says "START" and answer it.They look on the other strips to find where that answer is located. It could be anywhere on the remaining 15 problems.Once they find it, they answer the question that is on that strip.They will then connect the second strip to Strip A to create a paper chain.The

Swap x and y, solve for the new output and use inverse notation. The input-output diagram shows how inverse functions undo each other.
How To Invert The Function Keys In A Laptop
Do your students really understand inverse functions? To help students with this concept, they can investigate and discover it by using the basic understanding of an inverse and then apply it to finding the equation of a function's inverse.This discovery investigation will show students that the graphs of inverse functions are a reflection over the line y=x. Students will also identify that not all functions are invertible. Students should have familiarity with graphing linear functions and writing linear functions from a graph. They should have also already learned composition of functions.This resource also includes guided notes on how to find inverse functions algebraically and how to confirm functions are inverses by composition.You may also be interested in:Piece 'Em Up - Piecewise

How To Invert Function Keys
Read about how I teach my high school students about inverse functions. Start by inverting coordinates to teach inverse functions. Notice the geometric connection with the inverse as the reflection over the line y=x. Multiple representations are explored: tables, graphs and equations. Blog post by Mathberry Lane
Understand what f(4) means and learn how to evaluate a function by substituting the input into its formula.
This is a step-by-step with examples foldable for showing students how to find the inverses of functions. Fold it in the middle and cut along the black line between the halves then cut the foldable along all dotted lines to make four panels that fold into the center with the title at the top.
