Rational functions are mathematical expressions formed by the ratio of two polynomials. In more formal terms, a rational function \\( R(x) \\) can be expressed as: \\\[ R(x) = \\frac\{P(x)\}\{Q(x)\} \\\] where \\( P(x) \\) and \\( Q(x) \\) are polynomial functions, and \\( Q(x) \\neq 0 \\) (the denominator cannot be zero).
