If you want to keep your hint structure intact, you should add `data-ensure="K * J < 11"` or else make the graphing window taller.
As it is right now, the second point provided by the hints can end up off-screen. [Example: y = 4 * 3^x](http://sandcastle.khanacademy.org/media/castles/arnaudbenard:expo_log/exercises/expo_log.html?debug&problem=problem-type-or-description&seed=190)
