    Recall the definition of a polynomial. A n-order polynomial takes on the form of: \[y = ax^n + bx^{n-1} + ..+ px+ q\]

    Any of the coefficients of the terms can be 0.

    So \[3x^4\] is a polynomial too. It just means that the coefficient of all other terms is 0.

    Notice however, that all terms of polynomials have positive exponents.

    The degree of a polynomial would be the highest power. In this case, it is 6.
