$f (x) = \frac{x^{2} - x - 6}{x}$

Step 1

Factor $x^{2} - x - 6$ using the AC method.

Step 1.1

Consider the form $x^{2} + b x + c$ . Find a pair of integers whose product is $c$ and whose sum is $b$ . In this case, whose product is $- 6$ and whose sum is $- 1$ .

$- 3, 2$

Step 1.2

Write the factored form using these integers.

$f (x) = \frac{(x - 3) (x + 2)}{x}$

Step 2

Since no factors can be removed from the denominator, there are no holes in the graph.
