Determine whether the following function is a polynomial function. If the function is a polynomial function, state its degree. If it is not, tell why not. Write the polynomial in standard form. Then identify the leading term and the constant term. F(x)=4x6πx3+13F(x)=4 x^{6}-\pi x^{3}+\frac{1}{3}
Determine whether F(x)F(x) is a polynomial or not. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. A. It is a polynomial of degree \square (Type an integer or a fraction.) B. It is not a polynomial because the variable x is raised to the \square power, which is not a nonnegative integer. (Type an integer or a fraction.) C. It is not a polynomial because the function is the ratio of two distinct polynomials, and the polynomial in the denominator is of positive degree.
