Question

I also need help with this one too

Answer 1

Answer:

5x-1

Step-by-step explanation:

f(x) = 3x-2

g(x) = 2x+1

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

Combine like terms

            = 5x -1

Step-by-step explanation:

Step 1: Define

Identify

f(x) = 3x - 2

g(x) = 2x + 1

(f + g)(x) is f(x) + g(x)

Step 2: Find

1. Substitute in functions:                                                                                     (f + g)(x) = 3x - 2 + 2x + 1
2. [Addition] Combine like terms (x):                                                                   (f + g)(x) = 5x - 2 + 1
3. [Addition] Combine like terms:                                                                        (f + g)(x) = 5x - 1
