If x and f are quantities then xf and fx are the same if they belong to a commutative space. If not, they normally do not. Multiplication of matrices, for example is cont commutative. In fact, it is quite possible that xf has a value but fx does not even exist.
if x and f are functions then again, fx and xf will not generally be the same.
For example suppose x = "add 5 to it" and f = "square it".
Then xf(3) = x(9) = 14
while fx(3) = f(8) = 64
fx=5x1 / 9
if x is compact, you are simply multiplying the compact number, therefore, 'fx' will also be compact.

It depends on whether fx denotes frequency times variable value or the probability generating function for the variable x.
The cars are completely different classes. The X6 competes with infiniti FX,Porsche Cayenne, and Audi crossover(don't know the name). The Jaguar XF competes with luxury sports sedans like the BMW 5 series and Mercedes E class. As far as my personal preference, I think these crossover SUV's are ugly.
