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)

- 6. I'm preview now! Determine whether the following is a function relation. Y = + - x, y = x & #; When x = 1, y has two corresponding values, so y is not a function of X. when x = 1, - 1, y has a definite value of 1, so it is a functional relationship. So I want to ask, this problem does not tell who is a variable and who is a constant. Then I regard y as a variable, and when y = 1, x = + - 1, there are two corresponding values. Is it not a functional relationship? I'm a sophomore in junior high school. I just preview the new content tonight, Weak ask you big brother ~ swelling? Can only see x?
