Learn how to find inverse functions with step-by-step guidance and examples, enhancing your understanding of this fundamental algebra concept.

Sal explains what inverse functions are. Then he explains how to algebraically find the inverse of a function and looks at the graphical relationship between inverse functions. Created by Sal Khan.

In the first inverse function video, I talked about how a function and their inverse-- they are the reflection over the line y equals x. So where's the line y equals x here?

Explore the intriguing connection between inverse functions and their derivatives. We delve into the unique relationship that exists when f (g (x))=x=g (f (x)), using the functions 𝑒ˣ and ln (x) as examples.

A function will map from a domain to a range and you can think of the inverse as mapping back from that point in the range to where you started from. So one way to think about it is, we want to come up with …

An inverse function takes the output from the original function and gives us the input. Given a table of inputs and outputs for a function, evaluate the inverse function for a certain input.

Finding the Inverse or Showing One Does not Exist, Ex 4 (patrickJMT) Don't forget to come back and check your understanding with the practice exercises at Khan Academy - Finding Inverse Functions.

Hi - So the question is finding the inverse of function y=3x/x+1 I've gone through some of the steps to get to the point 3y=xy+x, but...

Practice finding the formula of the inverse function of a given linear function.

By starting out with a function, you know it passes the vertical line test by definition. However, for its inverse to be a function, it also has to pass the horizontal line test to insure the one-to-one …
