An elementary function is a type of function that is constructed using a finite combination of basic functions and operations. The fundamental types of elementary functions include: 1. **Polynomial Functions**: Functions of the form \( f(x) = a_n x^n + a_{n-1} x^{n-1} + \dots + a_1 x + a_0 \), where \( a_i \) are constants and \( n \) is a non-negative integer.
