What is this problem about?
This video covers rational functions. Horizontal asymptotes, slant asymptotes, vertical asymptotes, holes, domain, interval notation are included. These factors of the problem significantly contribute to our ability to graph the function. This problem however specifically does not deal with horizontal asymptotes. We focus on slant/vertical asymptotes and especially holes.
What does the viewer need to pay special attention to in order to understand?
In order to better understand this problem, you must pay attention to every single detail. In order to find the equation for slant asympote, you need not go further than y = mx + b. Once you have the needed information, you can forget about the remainder since it is not necessary to us at the moment. Also remember even if it seems like the graph is touching the asympotote, it never, ever does.
