    Actually that can't be done unless it says that f is differentiable.
    If we assume that is what the question means then
    what if \frac{d[-f(x-h)]}{dh}=~?.

    Since the problem says that f' (NOT f) is continuous, I think we can assume that f is differentiable!

    pnfuller, since the problem says "use L'Hopitals rule", perhaps you could begin by doing that?

    It does not show f' on this computer.
    It could be that the image is so dark.
    I wish we could ban posting questions as images.

    well how do you take the derivative of the numerator with all the different variables?
