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√(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)=(3)/(5)x^4-18x^2+5-(10)/(x^2)`, as:


`F(x)=(3)/(5)x^4-18x^2+5-10x^-^2`

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