SV#2: Unit G Concepts 1-7 - Finding all parts and graphing a rational function


This problem is about how to graph rational functions. This whole unit was an immediate jump into it so now it's all shown step by step in my lovely video for you! We start off from identifying the equation to finding vertical asymptotes, to holes (if there are any!), to domain, x-intercepts, y-intercepts, finding key points, and graphing the points! It sounds like a lot but when you work out all the steps, it shouldn't take you more than 10 minutes to do!

The very very very first thing you need to know is how to identify between a horizontal asymptote and a slant asymptote. (If you remembered the songs, this will be a piece of cake! Yum, I love cake!) The only new things you need to know is vertical asymptote and holes which can be a struggle but once you get the hang of it, it'll be a breeze! That's really all you need to know how to do because everything else is review such as finding domain, x-intercepts, y-intercepts, and plotting points on a graph! Also, don't forget to factor accurately! Since this is a slant asymptote, be sure when you perform long division that it is right!
