firstly, the word rational...is derived from ratio..which in simple terms ..is a fraction. a rational function, like all functions, must contain both an independent and dependent variable. The general form of a function is y = f(x), where y [the dependent variable] is based on the value of x [ the independent variable. So, to answer the question, a rational function, is one that involves a rational expression, such as y = 23x/2.
