Q. Which statement about
is correct?
![](https://media1.shmoop.com/images/precalculus/precalc_unit3_quiz_latek_35.png)
It looks like the x-axis at its ends.
It looks like the line y = 3 at its ends.
It looks like the line x = 3 at its ends.
It looks like the line y = x at its ends.
It looks like the line y = 3x at its ends.

y = -1
y = x
x = -1
y = 1
There are no horizontal asymptotes, silly.

Q. What are the vertical asymptotes of
?
![](https://media1.shmoop.com/images/precalculus/precalc_unit3_quiz_latek_42.png)
x = -1 and 3
x = -1, 1, and 3
x = -1, 3, and ±i
x = -1, 0, -1, and 3
Huh? We don't see any vertical asymptotes.
Q. Which of the following statements about horizontal asymptotes is false?
A rational function has a horizontal asymptote if the order of its numerator is less than or equal to the order of its denominator.
The x-axis is the horizontal asymptote of the rational function if the order of its numerator is smaller than the order of its denominator.
The line y = 1 will be the horizontal asymptote for the rational function
![](https://media1.shmoop.com/images/precalculus/precalc_unit3_quiz_latek_43.png)
If the order of the numerator is larger than the order of its denominator, the rational function has a slant asymptote.
The end behavior of a rational function always resembles a horizontal line.
