If you cannot read it, let me know.
The functions and their descriptions are:
- Polynomial:
and 
- Logarithm:

- Exponential

<h3>How to describe the functions?</h3>
The functions are given as:




The functions would be described based on the type of function they represent.
Functions that use the "ln" keyword are logarithmic functions, while functions that use the "e" keyword are exponential functions.
