Answer 2

Answer:

3x² + 5x +2 is a polynomial.

Step-by-step explanation:

A polynomial is an algebraic expression in which power of the variable is a whole number.

In i) option, power is -1/2 , hence not a polynomial.

in iii) option, power is y½ , hence not a polynomial.

in iv) option , y is in the denominator, when it will come to numerator, its power will change from 1 to -1 , ie - 4y‐1 . hence power is an integer but not a whole no. hence not a polynomial.
