A rational function is a type of mathematical function that can be expressed as the ratio of two polynomial functions. Specifically, a rational function can be written in the form: \\\[ R(x) = \\frac\{P(x)\}\{Q(x)\} \\\] where \\( P(x) \\) and \\( Q(x) \\) are polynomials, and \\( Q(x) \\) is not equal to zero.
