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.

Here's an analysis of each function:

A. For :

The term is an exponential function, not in the form of where is a non - negative integer. So is not a polynomial.

B. For :

This can be written as . Since the exponent of is , which is a negative integer, it does not meet the definition of a polynomial where the exponents of
