When you remove the exponential, there’s a minus in this case.
If you want to see it clearly, use :
a^x = exp(x*ln(a))
And since ln(1/2) =-ln(2)=-0,693. The inequality changes signs

To be honest, this looks a bit complicated. I just want to understand which answer is correct, mine x∈(−3;1) or this one x∈(−∞;−3)∪(1;+∞).

Could you please point out where I made a mistake?

This
If a^x < a^y.
You get x < y if a >1
You get x >y if 0<a<1
