UpStudy AI · Accepted Answer

To find $$ (f + g)(x) $$, you simply add the functions $$ f(x) $$ and $$ g(x) $$ together.

Given:
$$
f(x) = -2x^2 - 6x
$$
$$
g(x) = -x
$$

Adding them:
$$
(f + g)(x) = (-2x^2 - 6x) + (-x) = -2x^2 - 7x
$$

So, the sum of the functions is:
$$
(f + g)(x) = -2x^2 - 7x
$$
$$ (f + g)(x) = -2x^2 - 7x $$

What is \( (f+g)(x) \) ? \[ \begin{array}{l}f(x)=-2 x^{2}-6 x \\ g(x)=-x \\ \text { Write your answer as a polynomial or a rational function in simplest form. }\end{array} \]
