Answer: The correct option is

(A) (ƒ + g)(x) = 6x − 2.

Step-by-step explanation: We are given to find the value of (f + g)(x) for the following functions :

$f(x)=2x-5,\\\\g(x)=4x+3.$

We know that

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

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

So, we get

$(f+g)(x)\\\\=f(x)+g(x)\\\\=2x-5+4x+3\\\\=6x-2.$

Thus,
(f+g)(x)=6x-2.

Option (A) is CORRECT.
