Please, help me to understand this statement:
"For each value of y greater than 2*(3)^(1/2), the function f(x) is such that the equation f(x) = y has the form x = (y^2 + 12)/y
My interpretation is that the result of that function is 'y' and that the value of 'y' will depend on that equation. But 'y' must be greater than 2*(3)^(1/2).
Am I right?, please your comments.

Hi metallicafan,
Yes, you have interpreted this correctly.
As an aside though, this is far too complex for a typical GMAT function question. While you'll likely see one function question on Test Day, it's not going to look like this.

Yup, you've got it right: if y is greater than 2√3, then x = y + 12/y and f(x) = y. At that point you'd probably be asked which of the five answers could define the function, or something like that.
I don't think this is too hard for the GMAT - I had two function questions on the real exam that were at least as hard as this, though in different ways - but I think it'd be about 80th percentile in math, and perhaps not really their style.
