Let by P, Q polinomials functions ,then f(x)=P(x)/Q(x) is rational function & g(x)=sqrt(P(x)) is irrational function. ok!

Unlike rational and irrational numbers, the term "irrational function" is not used. The definitions above for rational functions are correct, a ratio of polynomials. Sqrt(x) is not a rational function, but it is an algebraic function, being a solution to y^2-x=0. The function e^x is not a rational function, but is called a transcendental function. The term "irrational function" is not commonly used.

A rational function can be expressed a ratio of polynomials.
Therefore I'd assume an irrational function cannot.
