Share the four possible answer choices, please.

Your  x^4+7x-3x^2-x^3 has a couple of missing coefficients.  It'd be easier to answer this question if you'd re-write  x^4+7x-3x^2-x^3 with the powers of x in descending order:

x^4 - x^3  - 3x^2 + 7x

and then insert the missing coefficients (which are all 1's):

1x^4 - 1x^3  - 3x^2 + 7x


See whether you can now share the given answer choices and pick the correct one from among them.
