Given that the definition field of function y = f (x) is [- 1 / 3,1 / 3], find function f (x) = f (AX)+
Given that the domain of function y = f (x) is [- 1 / 3,1 / 3], find the domain of function f (x) = f (AX) + F (x / a) (a > 0)

The domain of y = f (x) is 1 / 3 ≥ ax ≥ - 1 / 3 in [- 1 / 3,1 / 3] f (AX) - - 1 / 3 ≤ X / a ≤ 1 / 3 in [- 1 / 3,1 / 3] f (AX) - - 1 / 3 ≤ X / a ≤ 1 / 3 in [- 1 / 3a, 1 / 3A] in [- 1 / 3a, 1 / 3A] in [- 1 / 3a, 1 / 3A] in [- 1 / 3a, 1 / 3A] in [- 1 / 3 ≤ x ≤ 1 / 3] in [x / a]

If A-B = 1, then 9-A + B=_____ If the square of a + a = 0, then the square of 2A + 2A + 2008 is______ .
Fill in the blanks, there can be no process

1. 9-A + B = 9 - (a-b) = 9-1 = 8
2. Because the square of a + a = 0
So: 2A square + 2A + 2008 = 2 (square of a + a) + 2008 = 2008
Ensure accuracy~
