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)
