hello :
F(x) = 2x + 6, g(x) = 4x²
(f + g)(x)= f(x) +g(x) = 4x²+2x+6

Answer: The correct option is

(C)
4x^2+2x+6.

Step-by-step explanation: We are given the functions f(x) and g(x) as follows :


f(x)=2x+6,\\\\g(x)=4x^2.

We are to find the value of (f+g)(x).

We know that

for any two functions p(x) and q(x), we have


(p+q)(x)=p(x)+q(x).

So, we get


(f+g)(x)\\\\=f(x)+g(x)\\\\=2x+6+4x^2\\\\=4x^2+2x+6.

Thus, the required value is
(4x^2+2x+6).

Option (C) is CORRECT.
