Finding the Domain by Investigating Continuity
Connect domains of functions to continuity with a video that first shows how to find the domain of a cube root function. It then explains how this domain relates to the continuity of the function.

How to Find Removable Discontinuities
So that's why its called a removable discontinuity. By watching the video, viewers learn to classify discontinuities as either removable or non-removable. They then learn to write a modified function that removes any removable...

Infinite Limits
Is the limit infinite or DNE? The video works through an example of finding a vertical asymptote for a trigonometric function and determining the one-sided limits on each side of the vertical asymptote.
Khan Academy
Khan Academy: Algebra Ii: Graphing Rational Functions 4
Video shows an example of finding the horizontal and vertical asymptotes of a rational function. Also shows finding the behavior of the function as it approaches the asymptotes and uses this information to sketch a graph of the function....

Khan Academy: Algebra Ii: Graphing Rational Functions 2
Video shows an example of finding asymptotes of a rational function. Uses the asymptotes and the behavior near the asymptotes to graph the function. Includes an example of a rational function that does not have asymptotes. [8:20]

Khan Academy: Algebra: Asymptotes of Rational Functions
Video explains what asymptotes are and demonstrates how to determine the asymptotes of rational functions. Includes rules for horizontal asymptotes based on the highest power of the numerator and denominator of the rational function....
