Hello. I need help in finding the domain in questions 2, 4 and 6

(1 point) Let f(x) = v1 - x and g(x) = \\ 25 - x2. Find f + 9, f - 9, f . 9, and -, and their respective domains. 1. f + g = sqrt(1-x) + sqrt (25-x*2) 2. What is the domain of f + g ? Answer (in interval notation): (-5, 1] 3. f - g = sqrt(1-x) - sqrt (25-x^2) 4. What is the domain of f - g ? Answer (in interval notation): (-5, 1] 5. f . g = sqrt(1-x)sqrt (25-x^2) 6. What is the domain of f . g? Answer (in interval notation): (-5, 1] 7 . = sqrt(1-x)/sqrt (25-x*2) 8. What is the domain of 7 Answer (in interval notation): (-5, 1]
