    the inverse function of your function is the one that is made by reflecting the original function over line y=x.

    |dw:1444407136808:dw| it is certainly not B. look: your original function intercepts x-axis. The x-coordinate of this interception is negative. So the inverse function will have y-intercept at (0, y), where y is negative.
