If f(x) = 3x - 1 and g(x) = x + 2, find (f+ g)(x).<br>A. 3x - 3<br>B. 2x-3<br>C. 2x-1<br>D. 4x+1​
Veseljchak [2.6K]

Answer:

2x-3

Step-by-step explanation:

f(x) = 3x-1

g(x) = x+2

Find (f-g)(x), this means we need to subtract g from x.

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

Subtract the like terms:

3x -x = 2x

-1 -2 = -3

Combine them to get 2x-3
