Khan Academy: Analyzing Functions: Recognizing Features of Functions (Example 1)

Sal continues looking at function inverses in this video by showing two examples. In each example, he finds the inverse and shows the graph of both functions. His examples are with linear functions, but his first example shows a function...

Learn about functions and x-intercepts.

This video analyze a function to determine if it is odd or even, find out the limit as x approaches infinite and its relative maximum or minimum.

This video provides several examples of using the distributive properties of multiplication and division to rewrite expressions. Practice problems are available. [5:39]

A video exploring whether a function is represented by a given set of points. [4:06]

This video analyze the graph of a linear function.

Recognize if a given table contain a linear equation.

Video giving an overview of the square root sign. Positive values are then chosen to evaluate the basic quadratic and square root functions, the points are graphed, and the graphs are compared. Graphs are also created with an online...

Learn to find out the intervals when the function is is positive or negative.

Video showing how to solve for a function given a composition of functions and one of the functions. Also shows how the problem can be solved using the different multiple choice options. Includes link for additional practice at the top...
