Hi Sameer,
Please clarify the statement how is the global variable not working. What do you mean exactly?
Note that you are returning a parameter named f and you have declared a global variable with the same name. Why? There is no need to declare your return parameter as global.

You don't need to make f global if you're returning it to the caller. Why? Why do that? Declaring it global inside objfun means that f now takes on whatever value it had last instead of being a local variable. But then you just overwrite that value , so there was absolutely no point in making it global since you didn't even use its global value. Delete that global line of code.
