Please note that considering the function f(x), I can say that the radicands exist if and only if x >=0 and 7-x >=0
so the domain of f(x) is:
[0, 7], where x=0 and x= 7 are included into the domain
here we note that the radicand exist if and only if x+8 >=0, furthermore has to be xdifferent from zero, so the domain of g(x) is:
[-8 , 0) union (0, +infinity), here -8 is included into the domain
