Step 1.1

Divide each term in $x y = 6$ by $x$ .

$\frac{x y}{x} = \frac{6}{x}$

Step 1.2.1.1

Cancel the common factor.

$\frac{x y}{x} = \frac{6}{x}$

Step 1.2.1.2

Divide $y$ by $1$ .

$y = \frac{6}{x}$

Step 2

Find where the expression $\frac{6}{x}$ is undefined.

$x = 0$

Step 3

Consider the rational function $R (x) = \frac{a x^{n}}{b x^{m}}$ where $n$ is the degree of the numerator and $m$ is the degree of the denominator.

1. If $n < m$ , then the x-axis, $y = 0$ , is the horizontal asymptote.

2. If $n = m$ , then the horizontal asymptote is the line $y = \frac{a}{b}$ .

3. If $n > m$ , then there is no horizontal asymptote (there is an oblique asymptote).

Step 4

Find $n$ and $m$ .

$n = 0$

$m = 1$

Step 5

Since $n < m$ , the x-axis, $y = 0$ , is the horizontal asymptote.

$y = 0$

Step 6

There is no oblique asymptote because the degree of the numerator is less than or equal to the degree of the denominator.

No Oblique Asymptotes

Step 7

This is the set of all asymptotes.

Vertical Asymptotes: $x = 0$

Horizontal Asymptotes: $y = 0$

No Oblique Asymptotes
