Example Question #1 : Graph Rational Functions, Identify Zeros, Asymptotes, And End Behavior: Ccss.Math.Content.Hsf If.C.7d
Graph the following function and its asymptotes.
This question is testing one's ability to graph a rational function and identify its asymptotes.
For the purpose of Common Core Standards, "graph rational functions, identifying zeros and asymptotes when suitable factorizations are available, and showing end behavior." falls within the Cluster C of "Analyze Functions Using Different Representations" concept (CCSS.MATH.CONTENT.HSF-IF.C.7).

Recall that asymptotes occur at locations where the domain and range of the function do not exist. For vertical asymptotes this occurs if there is a fraction where the denominator contains the variable:
Given the function
thus a vertical asymptote is at .
Step 2: Identify the horizontal asymptote by examining the end behavior of the function.
Given the function
to find the end behavior, substitute in large values for x. When large values of x are put into the function the denominator becomes larger.
Recall that when n is some large value, the fraction approaches zero.
Therefore, the horizontal asymptote is at .
