SOLUTION: For f(x)=x^2 +2 and g(x) +3sqrt(x) would the formula be x^2+2+3sqrt(x)? And how do I figure out the domain?

If you are looking for f(x) + g(x) (or (f+g)(x) which means the same thing) then you are correct.

For the domain you are looking for the possible values for x. Any number can be squared. So the domain for f(x) is all Real numbers. Only non-negative (zero or positive) numbers have a square root so the domain for g(x) and f(x) + g(x) is
