Question

$x^7-4x^4+\frac{4}{x}-1$ is a polynomial.

• A. True
• B. False

Answer 1

The correct option is B False

We know that the algebraic expression in one variable is a polynomial if the index of variable of each term is a whole number.
In the given expression, the index of $x$ in the term $\frac{4}{x}$ is not a whole number and hence this expression is not a polynomial.
Therefore the given statement is false.
