D. The x in the function is not being manipulated, meaning it is not a horizontal shift. Therefore, it is a vertical shift. Since the shift is negative, the function is shifted 4 units down. Think about it: suppose f (x) = x. If g (x) = x - 4, then the function would just be the graph of x shifted down 4. Apply this logic to any equation and it works.
