In the nice Desmos demo, can you make the slider approach zero instead of going to infininty?

Do you mean approach zero by going right instead of left? I think that's impossible. I did edit the "scope" of the slider so it now stops at 5 instead of going so far right.

Looking at positive values is fine. But since we are interested in lim_{x \rightarrow 0+} it would be nice if the values of a decrease to zero, instead of increase away from zero. Maybe using -a instead would do the trick? Luxury problems :)

Kinda sorta hacked. Not really. But slightly better?

Slightly better, yes.

The hint is a good start, but does not lead to the key idea. Please improve or add a second hint.
