Questions on identifying graphs of rational functions are presented; their answers are also included.

Use all properties of rational functions such as range, domain, x-intercepts, y-intercepts, asymptotes, horizontal shift, vertical shift, compression and stretching to answer the questions suggested. Graph the function given before you answer your questions. The self test has a set of 10 questions on this page. The same questions may be accessed using thge applet below.

Graphs of rational functions questions with answers

You are given 4 graphs, select the best possible answer.

Question 1: Identify the graph of the rational function f.

f(x) = 1 / x

f(x) = 1 / (x - 1)

f(x) = (x + 1) / (x - 1)

f(x) = 1 / (x ² + x -2)

f(x) = (x + 2) / (x ² -1)

f(x) = (x + 2) / (x ² - x - 2)

f(x) = (x - 1) / (x ² + x + 1)

f(x) = (x ² + x -2) / (x ² - x - 2)

f(x) = 1 / (x ² + x + 1)

f(x) = (x ² - x) / (x ² - x - 2)
