Practice Question on System Stability
The input x(t) and the output y(t) of a system are related by the equation
$ y(t)=\frac{1}{1+x^2(t)}. $
Is the system stable? Answer yes/no and ustify your answer.

Answer 1
This system is stable. I'm actually not sure how to show this, does the following logic work?
$ \lim_{x(t) \to 0}\frac{1}{1+x^2(t)} = 1 $ and $ \frac{1}{1+x^2(t)} < 1 $ for all x(t), thus the system is stable.
I'm not sure that the justification works here...
