Step 1.1

Factor $4$ out of $- 4 x$ .

$y = \frac{x - 4}{4 (- x) - 16}$

Step 1.2

Factor $4$ out of $- 16$ .

$y = \frac{x - 4}{4 (- x) + 4 (- 4)}$

Step 1.3

Factor $4$ out of $4 (- x) + 4 (- 4)$ .

$y = \frac{x - 4}{4 (- x - 4)}$

Step 2

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