Question
State True or False, if the following expression is polynomial in one variable $($State reason for your answer$): \text{y}+\frac{2}{\text{y}} \ a.$ True $b.$ False

Answer

The expression $\text{y}+\frac{2}{\text{y}}$ contain the term $\frac{2}{\text{y}},$
Here the exponent of y is $-1$, which is not a whole number.
Therefore, the given expression is not a polynomial in one variable.
