Question
Is the expression $y + \frac{2}{y}$, polynomial in one variable or not? State the reason for your answer.
✓

Answer

$y + \frac{2}{y}$
We can observe that in the polynomial $y + \frac{2}{y}$ ,we have y as the only variable and the powers of y in each term are not a whole number.
Therefore, we conclude that $y + \frac{2}{y}$ is not a polynomial in one variable.
