Is the following expression a polynomial? Justify your answer:
$\frac{1}{2x}$
$\frac{1}{2x}$
(N/A) $\frac{1}{2x} = \frac{1}{2} x^{-1}$
Here,the exponent of the variable $x$ is $-1$,which is not a whole number.
$A$ polynomial is defined as an algebraic expression in which the exponents of all variables are non-negative integers (whole numbers).
Since $-1$ is not a whole number,this algebraic expression is not a polynomial.
