why doesn't this function have a graph for negative x values? is it because it oscillates too much?

there are an infinite number of discontinuities between 0 and -1 you would have to use a special numerical method to find the non-imaginary solutions

It's complex valued for x < 0.

(-x)^(-x) = (-1)^(-x) * x^(-x) = (-1)^x * real

(-1)^x is imaginary for every x except integers, so (-x)^(-x) is only real at

(-1)^(-1) = -1
(-2)^(-2) = 1/4
...
(-n)^(-n) = (-1)^n / n^n

thanks anon that kinda explains it. also, that's python, right? how long would it take me to learn python from 0 to the point where i could use it for math?

It's Wolfram Mathematica, although Python would be prefferable at least because there is a package for everything math related.
