Which of the following rational function is graphed below?

steposvetlana [31]

9514 1404 393

Answer:

B. 1/((x -1)(x -2))

Step-by-step explanation:

The vertical asymptotes at x=1 and x=2 tell you the denominator will have factors such that these values make it zero: (x -1)(x -2). That is sufficient to identify choice B as the correct answer.

$f(x)=\dfrac{1}{(x-1)(x-2)}$
