Let f(x)=7x+4 and g(x)=4x-5. Find (f + g)(x), (f g)(x), (fg)(x), and (x). Give the domain of each. (f+g)(x)=(Simplify your answer.) (f-g)(x)= (Simplify your answer.) (fg)(x)=(Simplify your answer.) (= (4)(x) = (Simplify your answer.) The domain of f + 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 Let f(x)=7x+4 and g(x)=4x-5. Find (f + g)(x), (f g)(x), (fg)(x), and (x). Give the domain of each.
