    A polynomial is a monomial or the sum or difference of monomials. Each monomial is called a term of the poynomial

    yeah, i think D is the only one that isn't because it has a negative exponent in it

    A polynomial is a sum of terms. Each term of a polynomial can only contain a number (called coefficient) and zero or more variables raised to a natural number (1, 2, 3, ...). If you have a variable as an exponent, or a variable raised to a negative exponenet, or a fractional exponent, that is not a polynomial.

    so A wouldn't be one either according to mathstudent's definition

    Ya, I don't think is a polynomial either.

    B & F are both polynomials @Katieann16

    actually E wouldn't be one either since it has x^4 in the denominator

    A has a variable as an exponent. C has a fractional exponent D & E have variables in the denominator

    To get this question right you have to understand the definition of a monomial.
