It's trivial to find a differential equation that a given function satisfies. For example, if f(x,y,z)= 2x^2- 2xyz- y^3+ e^z, then f satisfies f_x= 4x- 2yz.

Of course, given any function, there exit an infinite number of partial differential equations it satisfies, and any of those equations has an infinite number of other solutions.
