Let f(x)=1-sqrt(x-3) and g(x)= x-4
find the domains and formulas for the functions
f+g, f-g, f.g and f/g?

What are your thoughts? What have you tried? How far have you gotten? Where are you stuck? For instance, in the first operations-on-functions part (here), what did you get when you added the two polynomials? What did you get as being the domain of f(x)? So what did you get as being the domain of f(x) + g(x)? And so forth.

Please be complete. Thank you!
