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!

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.

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.
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 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.
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.
Evaluating Functions - Function Notation - MathHelp.com
By yourteachermathhelp
YouTube presents Evaluating Functions - Function Notation, an educational video resource on math.
Parent Functions
By Marty Brandl
This video looks at the parent functions: linear, quadratic, cubic, and square root. It includes five examples.
Graphs of piecewise linear functions
By Khan Academy
Sal explains what a piecewise function is, and finds the formula of a piecewise function given its graph.
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.

Finding Trigonometric Functions of Any Angle
Comparing linear functions
By Khan Academy
Sal is given a table of values of a linear function and four linear graphs, and is asked to determine which graph increases faster than the function represented in the table.
Comparing linear functions
By Khan Academy
Sal is given a table of values of a linear function and four linear graphs, and is asked to determine which graph has the same rate of change as the function represented in the table.
