Polynomial and Rational Functions

Functions of a polynomial nature involve mathematical expressions that are the sum of powers, which are multiplied by coefficients across one or more variables. Conversely, a function is considered rational if it can be defined by the proportion of two polynomials. These principles are crucial in both algebra and calculus, serving as the basis to explain numerous mathematical occurrences.
