Expert Answer:

In (i) the powers of x are 3, -2, -1, and 0. Since -2, -1 are not non-negative integers, therefore it is not a polynomial.

In (iii) the powers of the variable u are

_{}, 1, and 0. Since_{}is not non-negative integer, therefore it is not a polynomial.### Answered by | 26th Jul, 2017, 10:52: AM
