Answer:

(f+g)(x) = -8x-6

Step-by-step explanation:

We are given the two functions:

\displaystyle f(x) = -5x - 4 \text{ and } g(x) = -3x - 2

And we want to find:

(f+g)(x)

Recall that this is equivalent to:


\displaystyle (f+g)(x) = f(x) + g(x)

Substitute and simplify:

\displaystyle \begin{aligned} (f+g)(x) &= (-5x-4)+(-3x-2) \\ \\ &= -8x-6 \end{aligned}

In conclusion:

(f+g)(x) = -8x-6
