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!
Recognizing functions from graphs
By Khan Academy
Sal checks whether a given set of points can represent a function. For the set to represent a function, each domain element must have one corresponding range element at most.
Recognizing functions from graphs
By Khan Academy
Sal explains why a vertical line *doesn't* represent a function.
Graphs Of Square Root Functions
By Khan Academy
This Khan Academy video offers more information on graphing square root functions and contains a few sample problems with a step-by-step walkthrough on graphing these functions.

Function Inverse Example 1
Function inverses example 3 | Functions and their graphs | Algebra II | Khan Academy
By Khan Academy
Function Inverse Example 3: f(x)= (x - 1) squared -2 This is the last segment of Mr. Khan's short 4-part series on Function Inverses. These installments started with Khan's Introduction to Function Inverses. Mr. Khan uses the Paint Program (with different colors) to illustrate his points. Sal Khan is the recipient of the 2009 Microsoft Tech Award in Education. The screen gets busy (and dark)--the viewer may want to open to 'full screen' to see everything. The sound is a little low.

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.
Match graphs of rational functions to their formula
By Khan Academy
Sal matches three graphs of rational functions to three formulas of such functions by considering asymptotes and intercepts.

Graphs of linear equations | Linear equations and functions | 8th grade
By Khan Academy
A video that goes over graphing linear equations on the coordinate plane. The first part of the video starts with an equation with two variables, x and y. The instructor finds sample points and then plots them. Then, he moves on to some more complicated and conceptual problems.

Recognizing odd and even functions | Functions and their graphs | Algebra II | Khan Academy
By Khan Academy
This video shows us how to determine if a function is odd, even, or neither. One of the easiest ways to recognize even or odd functions is graphically. Even functions are symmetrical over the y-axis. Remember: A function is even if f(-x) = f(x) Odd functions are symmetrical over the origin. Remember: A function is odd if f(-x) = -f(x).
