Plot real to complex function

I have a function that has real domain and a complex co-domain. I want to plot the real and imaginary parts together, like this: imgur.com/a/yb7g5Ce

The code that I used to generate that plot (plot(real(F(x)),(-2,2)) + plot(imag(F(x)),(-2,2),color="red")) works, but I think every value is being calculated two times, discarding either the real or the imaginary part. Is there any way to get this effect more efficiently, without doing useless calculations?

From the Python documentation :

@functools.cache(user_function)

Simple lightweight unbounded function cache. Sometimes called “memoize”.

Returns the same as lru_cache(maxsize=None), creating a thin wrapper around a dictionary lookup for the function arguments. Because it never needs to evict old values, this is smaller and faster than lru_cache() with a size limit.

HTH,
