Answer:

$f(x) = \frac{\sqrt{x+2}} 9$

Step-by-step explanation:

You work in the order you have: you start with your number x, so your first step will be $f_0(x)=x$ . then you add 2: $f_1(x) =x+2$ . Then you take the square root of what you have in the previous step: $f_2(x) = \sqrt {x+2}$ . Finally, you divide by 9: $f(x) = \frac{\sqrt{x+2}} 9$
