The correct answers are:
(1)
√(3) - 3 ↔ (g+f)(2)
(2) 0 ↔ (
(f)/(g))(-1)
(3)
-3 * √(3) ↔ (g x f)(2)
(4)
( √(15)) ↔ (g-f)(-1)

Step-by-step explanation:
Box-1:

Step 1: Find (g + f)

( √(11 - 4x) + 1 - x^2) --- (1)

Step 2: Now Plug in x = 2 in (1) gives you (g+f)(2):

( √(11 - 4*2) + 1 - 2^2)
=>
√(3) - 3

Box-2:
Step 1: Find (
(f)/(g))

(1-x^2)/( √(11 - 4x) ) --- (2)

Step 2: Now Plug in x = -1 in (2) gives you (
(f)/(g))(-1):

(1-(-1)^2)/( √(11 - 4(-1)) ) \\ (0)/( √(15) ) \\ 0

Box-3:
Step 1: Find (f x g)

(1-x^2) * ({ √(11 - 4x) }) --- (3)

Step 2: Now Plug in x = 2 in (3) gives you (g x f)(2):

(1-(2)^2) * ({ √(11 - 4(2)) }) \\ -3 * √(3)

Box-4:
Step-1: Find (g-f):

( √(11 - 4x) - 1 + x^2) --- (4)
Step 2: Now Plug in x = -1 in (4) gives you (g-f)(-1):

( √(11 - 4(-1)) - 1 + (-1)^2) \\ ( √(15) - 1 + 1) \\ ( √(15))

The answers are:

\sqrt{3}-3 ------> (g+f)(2)
0 ------> (f/g)(-1)
-3(sqrt)(3) ------> (gxf)(2)
(sqrt)(15) ------> (g-f)(-1)
