no hay asíntota inclinada a la izquierda
$$\lim_{x \to \infty}\left(\frac{\left(x^{2} \left(x - 2\right) - 5 x\right) + \frac{4}{x - 4}}{x}\right) = \infty$$
Tomamos como el límite
es decir,
no hay asíntota inclinada a la derecha
$$\lim_{x \to -\infty}\left(\frac{\left(x^{2} \left(x - 2\right) - 5 x\right) + \frac{4}{x - 4}}{x}\right) = \infty$$

Paridad e imparidad de la función
Comprobemos si la función es par o impar mediante las relaciones f = f(-x) и f = -f(-x).
Pues, comprobamos:
$$\left(x^{2} \left(x - 2\right) - 5 x\right) + \frac{4}{x - 4} = x^{2} \left(- x - 2\right) + 5 x + \frac{4}{- x - 4}$$
- No
$$\left(x^{2} \left(x - 2\right) - 5 x\right) + \frac{4}{x - 4} = - x^{2} \left(- x - 2\right) - 5 x - \frac{4}{- x - 4}$$
- No
es decir, función
no es
par ni impar
