Question

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

Answer 1

See below.

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`
