I was wondering if we include asymptotes as criticals:(adsbygoogle = window.adsbygoogle || []).push({});

For example in y = x sqrt(4-x^2)

when u find the critical points it gives u root 2 and negative root 2

But when I draw the graph im missing the 2 and -2 which were the asymptotes which help define the graph?

So are they needed?

Thanks
