Answer 1

The correct answer is:  [B]:  "11" .
____________________________________________________
Explanation:
____________________________________________________
(f+g)(4)  =  f(4) + g(4) ;

Given:  f(x) = (x−2)² ;

            g(x) = (x+3) ;
____________________________________________
As such:

       f(4) = (4−2)² = 2² = 2*2 = 4 .

       g(4) = (4+3) = 7 .

____________________________________________
    (f+g)(4) = f(4) + g(4) = 4 + 7 = 11 .

The answer is:  [B]:  "11" .
