The graph of the function f(x) = log2(x - 6) can be obtained from the graph of g(x) = log2 x by one of the following actions: (a) shifting the graph of g(x) to the right 6 units; (b) shifting the graph of g(x) to the left 6 units; (c) shifting the graph of g(x) upward 6 units; (d) shifting the graph of g(x) downward 6 units; Your answer is (input a, b, c, or d) The domain of the function f(x) is x > A, find A The value of A is Is the range of the function f(x) still (-, )? Your answer is (input Yes or No)
