How to determine if discontinuities are holes or asymptotes
👉 Learn how to find the removable and non-removable discontinuity of a function. A function is said to be discontinuous at a point when there is a gap in the graph of the function at that point. A discontinuity is said to be removable...

Graph Rational Functions | Rational Functions | Pre-Calculus
Let's discover how to identify the asymptotes and intercepts of a rational function. We will begin graphing the reciprocal function and use that to help us understand the asymptotes and intercepts of any reciprocal function. I make...

Graphing a rational function with no horizontal asymptote
👉 Learn how to graph a rational function. To graph a rational function, we first find the vertical and horizontal or slant asymptotes and the x and y-intercepts. After finding the asymptotes and the intercepts, we graph the values and...

Determine the vertical asymptotes
👉 Learn how to find the vertical/horizontal asymptotes of a function. An asymptote is a line that the graph of a function approaches but never touches. The vertical asymptote is a vertical line that the graph of a function approaches but...

Graphing a rational functions with asymptotes
👉 Learn how to graph a rational function. To graph a rational function, we first find the vertical and horizontal or slant asymptotes and the x and y-intercepts. After finding the asymptotes and the intercepts, we graph the values and...

What is the Domain Range and Vertical Asymptote of Tangent
👉 Learn the basics of graphing a tangent and a cotangent function. To plot the tangent and the cotangent graph we choose a set of points and form a table of values with which we plot the points on the x-y coordinate axis to obtain the...

Horizontal and Vertical asymptotes of rational functions
👉 Learn how to find the vertical/horizontal asymptotes of a function. An asymptote is a line that the graph of a function approaches but never touches. The vertical asymptote is a vertical line that the graph of a function approaches but...

What you need to know | Rational Functions
In this video I present a set of problems to help prepare for learning about rational functions in precalculus. While rational functions is explored in Algebra 2 I decided to make it a separate unit in precalc based on how many students...

How to Find Vertical Asymptotes!!
Ascertain the asymptotes. An informative video describes how to algebraically determine the locations of vertical asymptotes for the graphs of rational functions. Scholars see that they need to set the denominator equal to zero and solve...

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.
