A function ff has domain [0,  2][0, \; 2] and range [0,  1][0, \; 1]. (The notation [a,  b][a, \; b] denotes {x  :  axb} \{ x\; : \; a \le x \le b \}.) What are the domain and range, respectively, of the function gg defined by g(x)=1f(1+x)g(x)=1-f(1+x) ?


(A) [1,  1],  [1,  0][-1, \; 1 ], \; [-1, \; 0]

(B) [1,  1],  [0,  1][-1, \; 1 ], \; [0, \; 1]

(C) [0,  2],  [1,  0][0, \; 2 ], \; [-1, \; 0]

(D) [1,  3],  [1,  0][1, \; 3 ], \; [-1, \; 0]

(E) [1,  3],  [0,  1][1, \; 3], \; [0, \; 1]
