Khan Academy: Analyzing Functions: Comparing Features of Functions 2 Example 1)

The example of two travelers meeting somewhere along the road has been a stereotypical joke about algebra as long as algebra has existed. Here in this detailed presentation, this old trope gets a careful and approachable treatment....

Here's a hint: look at the exponents. Scholars watch a video that shows two examples of how to algebraically prove whether a function is even or odd. They then see how the exponents in a polynomial function relate to the determination.

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...

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.

Learn what happens to different functions as the value of x increases or decreases.

Video continuing to show how to parameterize a torus using two parameters by writing the position vector valued functions. [16:32]

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

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...
