The function g (x) is a transformation of the parent function f (x = 2x . The graph of g(x) contains (-3, 1) , which is the image of (0, 1) on the graph of the parent function. The graph of g (x) also contains (-2, 3) , which is the image of (1, 2) on the graph of the parent function. Give the equation for g(x) , then graph g(x) .
