Let f(x) = 13x - 1 and g(x) = . Find (f +9)(x), (f -g)(x). (fg)(x), and | |(x). Give the domain of each. (f + 9)(x) =(Simplify your answer.) (f- 9)(x) =(Simplify your answer.) (fg) (x) = (Simplify your answer.) (x)= (Simplify your answer.) The domain of f+ g is. (Type your answer in interval notation.) The domain of f- g is. (Type your answer in interval notation.) The domain of fg is. (Type your answer in interval notation.) The domain of - is (Type your answer in interval notation.)
