    A polynomial is an expression that consists only of the addition, subtraction, and multiplication of non-negative integer exponents of variables and constants. They look like: x^2+2x+1, or x-50, or x^5+x^4+x^3+x^2+x+1

    So, you can't have 1/x as a term, for example. You can't have x^2/3 as a term either. But you can have x taken to any natural number power.

    can we call y=x^2 as polynomial

    x^2 is a polynomial. Polynomials are expressions, not equations

    that is a polynomial function

    Also, a negative power can't be a polynomial because then that includes division.

    Generally we name them after the number of terms they have, also. So if it is x+1, it's a binomial. x^2+x+1 is a trinomial. More than three terms is a polynomial.

    what qualifies polynomials is that the degree MUST be a non-negative integer (i.e. 1, 2, 3, 4, 5)

    0 is also okay for the degree because then it's the constant term :P

    so 2 is a polynomial...it has a degree of zero x is a polynomial with degree 1 x^2 is polynomial with dgree 2 and so on

    the degree has to be INTEGERS (non-negative)...which means whole numbers

    the exponent has to be a natural number. A number in the set {0,1,2,...}. No fractions or decimals or negatives allowed
