Ok, just did it for all of em and got the right answer (D)!
Although I see that picking small numbers and plugging would be a better strategy on test day, but wanted to understand the notation first :P
Thanks so much for your help!
Ah, I think I get it.
So to evaluate choice (A), I would do the following(?):
f(x) = 1 - x <-- set up provided by (A)
f(1 - x) = 1 - (1 - x) <--- plugging in (1-x) for x
f(1 - x) = x <--- restating
So now I have the two following statements:
f(x) = 1 - x
f(1 - x) = x
If I...
This is a problem from my GMAT practice exam that gives me the right answer but not an explanation as to why. The question is formatted as a data sufficiency question, which means that it asks you whether a pair of statements would be individually and / or together sufficient to answer the...

Because it is the only definition that can fit the impliciations of the words being used, as well as what people perceive it to mean.
Otherwise, you can say that the computer I'm sitting at right now has free will.

Plane on a treadmill
I read this puzzle recently,
There is a plane on an endless treadmill. The thing about this treadmill is that however fast the plane is moving forward, the treadmill goes the same speed backwards.
Would a plane be able to take off of this treadmill?
The only...
That's the same as asking "Can God create a rock so heavy that not even he could move it?"

I think we should evacuate jerusalem and then nuke it to the ground so that all that's left is a bunch of radioactive dirt.
