Defines the inverse of a function, an inverse function, and shows how to find the inverse of 1-1 functions.
  • What is the definition of the inverse of a function?
  • How do you find the inverse of a function?
  • How do you find the inverse of the function f = {(5, 3), (-1, 0), (4, 2)}?
  • How do you find the inverse of the function g = {(4, 1), (3, 1), (0, 1)}?
  • How do you find the inverse of the function f(x) = 3x - 4?
  • What does f^-1 mean if f is a function?
  • If f is a 1-1 function where f(-2) = 3 and f(1) = 4, what are two ordered pairs that belong to the inverse of f?
  • What are the steps for finding the inverse of a function?
  • How do you solve for y after you swap x and y in a function to find the inverse?
  • What do the graphs of a function and its inverse look like?
This lesson explains what the inverse of a function is, what it means to find the inverse of a function, and shows some examples of finding the inverse of some various functions. All steps involved are shown and explained clearly. This is a great tutorial on inverses of functions.
