Question

which one is not a polynomial (a) 4x^2+2x-1 (b) y+3/y (c) x^3-1 (d) y^2+5y+1​

Answer 1

Answer:

2) y+3/y

Step-by-step explanation:

The definition of a polynomial says that the power of a variable should be a whole number but in y+3/y the power of y is -1 because y raised to -1 is equal to 1/y

So This can be written as y+3×y^-1

As -1 does not belong to the group of whole numbers this cannot be a polynomial
