Please, help me to understand this statement:

"For each value of y greater than $$2\sqrt{3}$$, the function f(x) is such that the equation f(x) = y has the form $$x = \frac{y^2 + 12}{y}$$".

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 $$2\sqrt{3}$$.
