Question

let f (x) =- 3x and g (x) = 2x - 1 Find the following f (x) + g (x) Pleas show steps

Answer 1

Answer:

See below.

Step-by-step explanation:

So we have the two functions:

$f(x)=-3x\text{ and } g(x)=2x-1$

And we want to find f(x) + g(x).

So, substitute:

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

Combine like terms:

$=(-3x+2x)+(-1)$

Simplify:

$=-x-1$

So:

$f(x)+g(x)=-x-1$
