$f (x) = \sqrt{x - 10}$ $f(x)=sqrt(x-10)$ , $g (x) = - x$ $g(x)=-x$ , so
$f + g (x) = \sqrt{x - 10} - x$ $f+g(x)=sqrt(x-10)-x$

The domain would be $x \in [10, \infty)$ $x in [10, ∞)$ because $\sqrt{0}$ $sqrt0$ is possible, but $\sqrt{- 1}$ $sqrt(-1)$ is a math error (you can look into that if you're interested, $\sqrt{- 1}$ $sqrt(-1)$ is termed $i$ $i$ , stands for imaginary unit)
