Answer:

Step-by-step explanation:

We are given the two functions:

$f(x) = 8 - 4x - x^3\text{ and } g(x) = x^2 + 7x - 9$

And we want to find:

$f(x) + g(x)$

Substitute:

$= (8 - 4x - x^3) + (x^2 + 7x - 9)$

Rewrite:

$= (-x^3) + (x^2) + (7x - 4x) + (8 - 9)$

Combine like terms:

$= -x^3 + x^2 +3x -1$

In conclusion:

$f(x) + g(x) = -x^3 + x^2 +3x -1$

Hence, our answer is B.
