To determine which of the given functions is a polynomial, we need to identify whether the functions consist of terms with non-negative integer exponents. Polynomials are defined as expressions of the form:

where () are constants, and (n) is a non-negative integer.

 

Let's analyze each function:

A.

This is not a polynomial because the term has a negative exponent.

 

B.  

This is not a polynomial because the term
