Hi,

In the following code

MyOperator[g_][x_, y_] = 4 + Derivative[1, 0][g][x, y];

f[x_, y_] = x + y;
f[x_, y_, z_] = 2 x + 2 y + 2 z;

MyOperator[f][x, y]


how does Mathematica know which f to send to MyOperator. Can someone 
outline the formal decision tree that Mathematica follows?

Thanks!

Sam
