Question 3 of 10
Which of the following rational functions is graphed below?
A. F(x)=x/3
B. F(x)= x/(x+3)
C. F(x)=x-3/x
D. F(x)=3/x

Answer 1

B

Explanation:

Notice that at x=-3, we have a vertical asymptote

Ao our denominator should have (x+3) in the denominator.

The only answer here is B.

Also notice how both the numerator and denominator largest degree is 1, this if we divide their coefficients

(1/1)=1, that gives us our vertical asymptote.

Which is y=1.

So the correct answer is B.
