Each function out of the given 4 functions has a horizontal asymptote.
What is an asymptote?
An asymptote is a straight line that continually approaches a given curve but does not meet it at any finite distance.
Mathematically, if y=k is a horizontal asymptote for a function x=f(y) the limiting value of the function is infinity as y→k.
Out of the given curves, for every curve limiting value of the function tends to infinity as y→0
So, each function out of the given 4 functions has a horizontal asymptote.
Therefore, each function out of the given 4 functions has a horizontal asymptote.
