For the given functions, find (f o g)(x) and (g o f)(x) and the domain of each. f(x) = 9/1 - 7x, g(x) = 1/x (f o g)(x) = (Simplify your answer.) (g o f)(x) = Simplify your answer) What is the domain of f o g? A. (- infinity, 7) Union (7, infinity) B. (- infinity, 0) Union (0, infinity) C. (-infinity, -7) Union (-7, 0) Union (0, infinity) D. (-infinity, 0) Union (0, 7) Union (7, infinity) What is the domain of g o f? A. (-infinity, 0) Union (0, 1/7) Union (1/7, infinity) B. (-infinity, 0) Union (0, infinity) C. (-infinity, 1/7) Union (1/7, infinity) D. (-infinity, 7) Union (7, infinity)
