9. Find the formulas for the functions f+ 9, f-g, and fg. Give the domain of each. f(x) = x and g(x) = 4x - 7 f+g= (Simplify your answer.) The domain of f+ g is (Type your answer in interval notation.) f-g= Simplify your answer.) The domain of f - g is (Type your answer in interval notation.) fg = (Simplify your answer.) The domain of fg is Type your answer in interval 10. Find (f o g)( - 2) and (g o f)( - 2). f(x) = 4x - 1; g(x) =x -1 (f o g)( - 2) = (g o f)( - 2) = 11. Find f(g(x)) and g(f(x)). State the domain of each. f(x) = 4x + 3; g(x) = x - 2 What is the formula for f(g(x))? f(g(x)) = (Simplify your answer.) What is the domain of f(g(x))? (Type your answer in interval notation.) What is the formula for g(f(x))? 9(f(x)) = (Simplify your answer.) What is the domain of g(f(x))? (Type your answer in interval notation.) 12. Find f(x) and g(x) such that h(x) = (fog)(x). h(x) = 15x +4 Suppose that g(x) = 5x + 4. f(x) = 13. Find f(x) and g(x) so that the function can be described as y = f(g(x)). y = 6x + 5/ f(x ) =[ g(x) =
