Answer
All rational functions can be expressed as
$f\left( x \right)=\frac{p\left( x \right)}{q\left( x \right)},$ where p and q are polynomial functions and $q\left( x \right)\ne 0$.
Work Step by Step
Rational functions are quotients of polynomial functions which means that p and q are polynomial functions and $q\left( x \right)\ne 0$.
