Answer: The correct option is (A) 
Step-by-step explanation: We are given the following two functions :

We are to find the value of 
We know that
for any two functions p(x) and q(x), we have

Therefore, we get

Thus, option (A) is CORRECT.
<span>f(x)=2x+1 and g(x)=x^2-7
(f+g)(x) = </span>2x + 1 + x^2 - 7
(f+g)(x) = x^2 + 2x - 6
answer
x^2 + 2x - 6
