Question 24 of 25 > Th Th K Find f + g, f- g, fg and -. Determine the domain for each function. g f(x) = 5x +6, g(x) =x+5 (f + 9)(x) = (Simplify your answer.) What is the domain of f+ g? O A. The domain of f+ g is . (Type your answer in interval notation.) O B. The domain of f+ g is {}. (Use a comma to separate answers as needed.) O c. The domain off+ g is 8. (f -9)(x) = (Simplify your answer.) What is the domain of f- g? O A. The domain of f- g is .(Type your answer in interval notation.) O B. The domain of f - g is { }. (Use a comma to separate answers as needed.) O c. The domain off- g is 8. (fg)(x) = (Simplify your answer.) What is the domain of fg
