Question

Please please help!!

Answer 1

x must not be equal to zero
x=0 is an asymptote

The answer for the question is the 3rd option y= 0

Answer 2

In f(x):
x must be different to zero, then x=0 is an asymptote
When x tends to -infinite or x tends to + Infinite, the function f(x) tends to zero, then y=0 is an asymptote.

In g(x):
x-1 must be different to zero, then x=1 is an asymptote
When x tends to -infinite or x tends to + Infinite, the function g(x) tends to zero, then y=0 is an asymptote.

Answers:
Third option: y=0
