👉 In mathematics, a pretorsional function is a function that can be considered as a special case of a rational function. Specifically, if f(x) = p(x)/q(x), where p and q are polynomials and there exists a constant c such that |p(x)| ≤ c|q(x)| for all x in the domain of f, then f is said to be pretorsional. This means that the numerator p(x) can be considered as the polynomial part of the function
