      Introduction to functions


      By Khan Academy

      An introduction to functions.

          Understanding inverse trig functions


          By Khan Academy

          Sal is given the graph of a trigonometric function, and he discusses ways in which he can change the function to make it invertible.

              Model situations by composing functions


              By Khan Academy

              Given the formula of the volume of fuel in a tank as a function of its depth, and the formula of the depth as a function of time, Sal finds the formula of the volume as a function of time, by using function composition.

                  Comparing linear functions


                  By Khan Academy

                  Sal is given the formula of a linear function and the graph of another, and is asked to determine which function increases faster.

                      Verify that two functions are inverses


                      By Khan Academy

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

                          Inverse Relations and Functions


                          By WOWmath.org

                          This videos details the steps on how to find the inverse of a function.

                              Inverse Functions - The Basics!


                              By PatrickJMT

                              Inverse Trigonometric Functions http://www.youtube.com/watch?v=bBBUMHe900U All of the fundamental ideas of inverse functions are discussed. What exactly is an inverse function conceptually? Which functions have inverses? How do I graph inverse functions? What are the other basic relationships? I do not actually show how to find an inverse (I thought the video was getting too long!). I also already have videos about how to find inverses, so I will provide a link somewhere!

                                  Comparing features of functions


                                  By Khan Academy

                                  Sal is given the formula of one function and the graph of the other, and he determines which features are shared by both functions.

                                          Graphs of piecewise linear functions


                                          By Khan Academy

                                          Sal graphs a piecewise function given its formula. In this case, the function consists of three separate lines.

                                              By Khan Academy

                                              Sal explains what a piecewise function is, and finds the formula of a piecewise function given its graph.
