f(X) & f(X-1)

[LSB]

Is there a quick way to see the solution for this?

I'm not sure if its a quick solution...
but i have a solution.

Take x = 2

1. f(x) = -1
2. f(x) = -3
3. f(x) = 3
4. f(x) = 4
5. f(x) = -1

Since f(x) = f(1-x)

2-1 = -1

now for x = -1

1. f(x) = 2
2. f(x) = 0
3. f(x) = -1
4. f(x) = 4
5. f(x) = -1/2

for Option 4 f(x) = f(1-x)
