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]
