If G (x) satisfies g (1-x) + G (1 + x) = 1, then the coordinate of vector a is () A. (-1,-1)B. (2,32)C. (2,2)D. (-2,-32)

If G (x) satisfies g (1-x) + G (1 + x) = 1, then the coordinate of vector a is () A. (-1,-1)B. (2,32)C. (2,2)D. (-2,-32)

Function f (x) = X3 + 3x2 + 3x = (x + 1) 3-1, the center of symmetry is a (- 1, - 1), ∵ g (1-x) + G (1 + x) = 1, we know that the center of symmetry of curve g (x) is B (1,12), then according to the definition of vector translation, we know that a = AB = (1 - (- 1), 12 - (- 1)) = (2,32), so we choose: B (1,12)
