Answer 1

Justification that the expression $\frac{1}{x}+1$ is polynomial.

Polynomial: An algebraic expression where exponents of variables are all whole number.

The given expression is in the form, $\frac{1}{x}+1$, it can be written as, $x^{-1}+1$.

Thus, in the given expression the exponents of variable is not all whole number.
