Question

Is it polynomial or not? Give reason : f(x)=x + 1 x

Answer 1

Answer:

No

Step-by-step explanation:

it is not a polynomial. It is a binomial as it contains only 2 terms that are:- x and 1/x

Answer 2

x + 1/x = x + x^(-1)

So, this expression is clearly not a polynomial because polynomials cannot have negative powers on the variables.
