Let f(x) = 7x+2 and g(x) = 4x – 5. Find (f+g)(x). (f-9)(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.) (9) – [] (simplify your answer) The domain off+g is (Type your answer in interval notation.) The domain off-gis (Type your answer in interval notation.) The domain of fg is (Type your answer in interval notation) The domain of (Type your answer in interval notation)
