+118723 Well you cannot divide by 0 so 0 is one of the numbers.
1+1/x can also not equal zero so x cannot be -1
Also if you simplify this down you get to a point where
$$f(x)=\frac{1}{\frac{2x+1}{x+1}}$$
You cant divide by 0 so 2x+1 not eqal 0
x not equal -1/2
So the domain does not include 0,-1/2 or -1
the sum of these is -3/2
I have not checked any of my working. :)
