The other type of asymptote is a horizontal asymptote. They are lines parallel to the x-axis. 🚂

Therefore, to find horizontal asymptotes, we simply evaluate the limit of the function as it approaches infinity, and again as it approaches negative infinity. A function can have at most two horizontal asymptotes, one in each direction. ♾️
