 lim 20
x->oo  
$$\lim_{x \to \infty} 20$$
Limit(20, x, oo, dir='-')
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
The graph
Other limits x→0, -oo, +oo, 1
$$\lim_{x \to \infty} 20 = 20$$
$$\lim_{x \to 0^-} 20 = 20$$
More at x→0 from the left
$$\lim_{x \to 0^+} 20 = 20$$
More at x→0 from the right
$$\lim_{x \to 1^-} 20 = 20$$
More at x→1 from the left
$$\lim_{x \to 1^+} 20 = 20$$
More at x→1 from the right
$$\lim_{x \to -\infty} 20 = 20$$
More at x→-oo
