Answer 2

A, C, and E are all polynomial functions.

Polynomial functions must have terms that have non-negative integer exponents.  We can rewrite function B, $F(x)=-x^3+5x^2+7\sqrt{x}-1$ as:

$F(x)=-x^3+5x^2+7x^1^/^2-1$

The exponent 1/2 is not an integer exponent.

We can also rewrite the function D, $F(x)=\frac{3}{5}x^4-18x^2+5-\frac{10}{x^2}$, as:

$F(x)=\frac{3}{5}x^4-18x^2+5-10x^-^2$

We have a negative exponent, so this is not a polynomial.
