Respuesta :

(f+g)(x) = f(x) + g(x)

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

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

(f+g)(x) = 5x - 1

Answer:

5x-2

Step-by-step explanation:

If f(x) = 3x – 2 and g(x) = 2x + 1

we need to find (f + g)(x)

[tex](f + g)(x)= f(x) + g(x)[/tex]

Replace f(x) and g(x) in the given equation

[tex](f + g)(x)= f(x) + g(x)=3x-3+2x+1[/tex]

Now we combine like terms

[tex](f + g)(x)= f(x) + g(x)=3x-3+2x+1=5x-2[/tex]

[tex](f + g)(x)=5x-2[/tex]
