Answer:

no because degree of a polynomial is greater than or equal to one but in this equation the degree is -1 as b/x=b*x^-1

Step-by-step explanation:

no, a+b/x is not a polynomial because if you see

a+b/x we can write it as a+bx^-1 . Here the exponent of 'x' should not be in negative or irrational values . It should be at whole number only ...
