Answer 1

D. –x^4 + 6x^3 + 7x^2 – 4x – 4

Explanation:

When writing in standard form you have to put the monomials from greatest to least according to their exponent.

`-x^4+6x^3+7x^2-4x-4`

The first number is
`-x^4` because 4 is the greatest exponent we see, then comes
`+6x^3` which is next because it has the second greatest exponent. And so on and so on.
