Given the function `f(x)=9/(x+1)` and `g(x)=sqrt x` determine fog(x) and its domain.

The function `f(x) = 9/(x + 1)` and `g(x) = sqrt x` .

`fog(x)` = `f(g(x))` = `f(sqrt x)` = `9/(sqrt x + 1)`

**The function for `fog(x) = 9/(sqrt x + 1)` and the domain of the function is all values of x `>=` 0.**
