In mathematics, a rational function is any function that can be defined by a rational fraction, which is an algebraic fraction such that both the numerator and the denominator are polynomials. The coefficients of the polynomials need not be rational numbers; they may be taken in any field K. In this case, one speaks of a rational function and a rational fraction over K. The values of the variables may be taken in any field L containing K. Then the domain of the function is the set of th… WebJul 12, 2024 · Rational functions, of course, can have "holes" because they are continuous everywhere except where we would divide by zero; e.g., f ( x) = x − 1 x − 1 is a rational function whose graph looks like the graph of the constant function y = 1 except there is a point missing at x = 1.
