To draw the inverse function f^(-1), we reflect the graph of f over the line y = x. We can see that in the given graph of f, the function is one-to-one (passes the horizontal line test) and is decreasing from left to right. Therefore, the inverse function will also be one-to-one and decreasing. The only graph that fits this description is A. B would not be a valid inverse because it is increasing instead of decreasing.
