@xichyu look up your exponent rules involving square roots and then remember the power rule from way back when in calc I. This is literally the easiest calc problem ever.

@xichyu do you mean f(0) = 0?

To get f(x), just perform integration on both sides of the equation. You get f(x) equals to integrated square root of f(x), where f(0) is 0.
