1 1 + 3x 9. (4 pts) Find f(g(x)) and g(f (x)) where f (x) = and g(x) = -. What does this tell us about x - 3 the relationship between f and g? 10. (3 pts) Find a domain on which f = (x + 4)2 is one-to-one and non-increasing, then find the inverse of f restricted to that domain. 11. (3 pts) Find a domain on which f = x2 - 5 is one-to-one and non-decreasing, then find the inverse of f restricted to that domain
