    what do you mean "no idea" ???

    you wouldn't have been assigned this problem unless you know something with regards to finding an implicit derivative.

    can you find the first derivative? that would be a good start.

    It should be clear that y = \pm 2 \sqrt{x} and you ought to have been taught how to differentiate this sort of thing. So where are you stuck?
