## Definition

This `AdaptableUnaryFunction` computes \( p(-x)\) for a given polynomial \( p\).

Note that this functor operates on the polynomial in the univariate view, that is, the polynomial is considered as a univariate polynomial in one specific variable.

This functor is provided for efficiency reasons, since this operation just flips the sign of all odd coefficients with respect to the specified variable.
