Answer:
For x = -4
f (x) = x + 2
We evaluate the value of x = -4
f (-4) = (-4) + 2
f (-4) = -2
Answer is : f (-4) = -2
For x = 4
f (x) = -2x + 4
We evaluate the value of x = 4
f (4) = -2 (4) +4
f (4) = -8 + 4
f (4) = -4
Answer is : f (4) = -4
For x = 0
f (x) = 3x -4
We evaluate the value of x = 0
f (0) = 3 (0) -4
f (0) = 0-4
f (0) = -4
Answer is : f (0) = -4
