X^33333333333333333 doesn't draw correctly it draws -x to infinity

When i plotted the function x^33333333333333333

I saw

The arm towards negative infinity goes up instead of down.

But I expected the arm towards negative infinity to go down

This is very easy to check (-1)^33333333333333333 is equal to -1 because 33333333333333333 is odd. But when you see the graph it reads 1.

I think there are maybe some overflow problems.

Yes, those are overflow problems:
the biggest integer number that demos can handle is: 2^53-1
now: log(2^53) = 15.95
and: log(33333333333333333) = 16.5
so you are exceeding the calculation capacities.
