Question

Which function(s) have horizontal asymptotes of y = 0

Answer 1

See below

Explanation:

A rational function has a horizontal asymptote of y=0 if the degree of the numerator is less than the degree of the denominator. For example, if
`f(x)=(x+1)/(x^2-3)`, then there's a horizontal asymptote at y=0 because the end behavior of the function is
`f(x)\approx(x)/(x^2)=(1)/(x)` where the outputs will approach zero.
