Limit(-6/x, x, oo, dir='-')
Detail solution
Let's take the limit
$$\lim_{x \to \infty}\left(- \frac{6}{x}\right)$$
Let's divide numerator and denominator by x:
$$\lim_{x \to \infty}\left(- \frac{6}{x}\right)$$ =
$$\lim_{x \to \infty}\left(\frac{\left(-1\right) 6 \frac{1}{x}}{1}\right)$$
Do Replacement
$$u = \frac{1}{x}$$
then
$$\lim_{x \to \infty}\left(\frac{\left(-1\right) 6 \frac{1}{x}}{1}\right) = \lim_{u \to 0^+}\left(- 6 u\right)$$
=
$$- 0 = 0$$
The final answer:
$$\lim_{x \to \infty}\left(- \frac{6}{x}\right) = 0$$
$$\lim_{x \to \infty}\left(- \frac{6}{x}\right)$$

Lopital's rule
There is no sense to apply Lopital's rule to this function since there is no indeterminateness of 0/0 or oo/oo type
