### What is Meant by Rational Functions?

In mathematics, a rational function is a function, where the function is in the fractional form. It means that the function should be of a/b form, where a and b are numerator and denominator respectively. In the rational function, both a and b should be a polynomial expression. But the coefficients of the polynomial need not be rational numbers. The standard form of a rational function is given by
Rational Function, R(x) = P(x)/ Q(x)
Here P(x) and Q(x) are polynomials, where Q(x) is not equal to 0.
