Question

I need a walk through please 1​

Answer 1

`f(x) = \frac{√(x+2)} 9`

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{√(x+2)} 9`
