Answer:

[tex](f+g)(x) = x^2 + 4x - 4[/tex]

Step-by-step explanation:

We are given these following functions:

[tex]f(x) = 4x + 2[/tex]

[tex]g(x) = x^2 - 6[/tex]

(f+g)(x)

We add the common terms. Thus:

[tex](f+g)(x) = f(x) + g(x) = 4x + 2 + x^2 - 6 = x^2 + 4x + 2 - 6 = x^2 + 4x - 4[/tex]

Thus:

[tex](f+g)(x) = x^2 + 4x - 4[/tex]
