Algebra-2

To determine which of the given functions is a polynomial, we need to check whether each function consists only of terms with non-negative integer exponents of (x). A polynomial can be expressed in the general form:

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

 

Let's analyze each function:

A.

This is a polynomial because all terms have non-negative integer exponents (2, 1, and 0).

 

B.

This is not a polynomial. The term can be rewritten as , which has a negative exponent.

 

C.
