A rational function is a function that is the ratio of polynomials. Any function of one variable, x, is called a rational function if, it can be represented as f(x) = p(x)/q(x), where p(x) and q(x) are polynomials such that q(x) ≠ 0.For example, f(x) = (x 2 + x - 2) / (2x 2 - 2x - 3) is a rational function and here, 2x 2 - 2x - 3 ≠ 0.. We know that every constant is a polynomial and hence ...
