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 \(\displaystyle f'\) on this computer.
It could be that the image is so dark.
I wish we could ban posting questions as images.
