Liebe Superuebersetzer
Wenn ganzrationale Funktion = absolute functions,
was ist "gebrochenrationale Funktionen"? Ist es "fraction function"?
Kontext: Ableitungsregeln für ganzrationale, gebrochenrationale und verkettete Funktionen kennen und sicher anwenden können
Vielen Dank!

general rational function
i.e. one which is not "proper" and must be decomposed into a sum of proper rational functions.

Ganzrationale Funktionen
Die allgemeine Form der ganzrationalen Funktion, auch Polynom genannt, sieht folgendermaßen aus:
f(x) = a0 + a1x1 + a2x2 + a3x3 + ... + anxn n ; a0 0
a0, a1, ... , an sind konstante Werte aus , wie z.B. 1, 3.2 oder ¾.

Gebrochenrationale Funktionen
Sind g(x) und h(x) Polynome, also ganzrationale Funktionen, so nennt man die Funktion
f(x) = g(x) / h(x)
gebrochenrationale Funktion.
http://www.netalive.org/rationale-funktionen/chapters/3.html
In the case of one variable, x, a function is called a rational function if and only if it can be written in the form
f(x) = P(x)} /Q(x)
where P, and Q, are polynomial functions in x, and Q is not the zero polynomial.
http://en.wikipedia.org/wiki/Rational_function
A quotient of two polynomials P(z) and Q(z),
R(z)=(P(z))/(Q(z)),
is called a rational function, or sometimes a rational polynomial function. More generally, if P and Q are polynomials in multiple variables, their quotient is called a (multivariate) rational function. The term "rational polynomial" is sometimes used as a synonym for rational function. However, this usage is strongly discouraged since by analogy with complex polynomial and integer polynomial, rational polynomial should properly refer to a polynomial with rational coefficients.

Integer Polynomial
A polynomial of the form
f(x)=a_nx^n+a_(n-1)x^(n-1)+...+a_1x+a_0
having coefficients a_i that are all integers. An integer polynomial gives integer values for all integer arguments of x (Nagell 1951, p. 73). The set of integer polynomials is denoted Z[x]. Integer polynomials are sometimes also called "integral polynomials," although this usage should be deprecated due to its confusing use of the term "integral" as an adjective.
An integer polynomial is called primitive if the greatest common divisor (a_0,a_1,...,a_n)=1.

Discussion
"improper rational function" is possible but personally I prefer "general"
So, the "ganzrationale Funktion" is "proper rational function"?
