Answer
not a polynomial
Work Step by Step
Polynomials consist of one or more monomials and have the form:
$$a_nx^n+a_{n-1}x^{n-1}+...+ a_1x+a+0$$
where $x$ is the variable, $a_n$ is the leading coefficient, and $n$ is a non-negative integer called the degree.
We can rewrite the given expression as
$$\frac{3}{x}+2=3x^{-1}+2$$
We see that this is not a polynomial because we have $x$ with a negative exponent.
