## What is a polynomial function?

A polynomial function is a function that can be expressed as a sum of terms, where each term is a product of a constant and a variable raised to a non-negative integer power. For example, the following function is a polynomial function:

```
f(x) = 2x^3 + 3x^2 - 5x + 1
```
