  1. Recognizing a Polynomial Function

    Which of the following are not polynomial functions? Explain.

    1. f(x)=5x2+4x−3x−1+2f(x) = 5x^{2}+4x-3x^{-1}+2
    2. f(x)=−x3+6x12f(x) = -x^{3}+6x^{\frac{1}{2}}
    3. f(x)=(x+3)(x−3)f(x) = (\sqrt x + 3)(\sqrt x - 3)
    4. f(x)=x5+πx−7x2+311f(x) = x^{5}+\pi x-\sqrt7 x^{2}+\frac{3}{11}
