Limits and Continuity
Infinite limit happens when there is a vertical asymptote. For horizontal asymptotes, a value is approached by the function as x goes to positive and negative infinity. What is the limit at an asymptote? Infinite limits are found in vertical asymptotes as x approaches a number. Finite limits ...
Hence, a graph of a function will get closer and closer to the line but will never touch it at any finite distance. This line may be horizontal, vertical, or slanted (sometimes called oblique). Below are examples of asymptotes of functions : Function with horizontal and vertical asymptotes...
Comparing Vertical and Horizontal Asymptotes A rational function is undefined at a vertical asymptote. The limits as or as will be the same if the function has a horizontal asymptote. 7.1.1 Graph the function in a [-20, 20, 5] x [-10, 10, 2] window. Use the graph to estimate th...

Question 6: Do the limit exist at vertical asymptotes? Answer: It refers to a place where the function is undefined and the limit of the function does not exist. It happens because s 1 approaches the asymptote, even small shifts in the x-value lead to subjectively large fluctuations in the...

In order for f to have a vertical asymptote at x = a, at least one of the limits above must be an infini imit, and f must be discontinuous at x = a. We know that polynomial functions are continuous for all real numbers, so a polynomial has no vertical asymptotes. Ba t/Ziegler/...
