Question

Which of the following rational functions is graphed below?

O A. F(X) =
2x
x(x - 2)
B. F(x) =
1
x(x - 2)
C. Fix) =
1
x(x - 2)
D. F(x) =
x + 1
(x + 2)(x +0)

Answer 1

Huh? I'm not sure what you're asking try C

Answer 2

• B. f(x) = 1/x(x - 2)

Explanation:

The graphed function has two vertical asymptotes.

• The functions A and D have degree 1 on the numerator and degree 2 on the denominator, so finally having degree 1, have one vertical asymptote, therefore discounted.

We are left with B and C.

Function B has vertical asymptotes 0 and -2.

• This is matching the graph, correct

Function C has vertical asymptotes 0 and 2

• This is not matching the graph, incorrect
