Graph Of All Inverse Trigonometric Functions
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
The inverse of an exponential function is a logarithmic function. The inverse of a function is obtained by switching the x and y coordinates. This reflects the graph about the line y=x. As you can tell from the graph to the right, the logarithmic curve is a reflection of the exponential curve.

Swap x and y, solve for the new output and use inverse notation. The input-output diagram shows how inverse functions undo each other.
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

Inverse Functions as GraphsStudents will investigate inverse functions by finding the equation of an inverse function, finding a table of points for an original and inverse function, and graphing both a function and its inverse on a coordinate grid. This no prep activity contains two pages of practice problems (6 problems total) and a two-question multiple choice homework assignment or exit ticket, as well as a full answer key. Just make your copies and it's ready to go!For each problem, students are given the equation of an original function and asked to complete a table of values for that function. Then students will need to also find the algebraic inverse and a table of values for the inverse. Using the table, students will then graph the function and its inverse together on the same gr
