Let 1 ms) = x/9x2, and gm = 3% (a) (2 points) Find the natural domains of f and 9. You may state the domains Without proof. (b) (3 points) Which of the functions are injective? For the functions that are injective, nd their inverse and state their natural domains. Show your workings clearly. (c) (2 points) Find the domain of g o f. Show your workings clearly. (d) (3 points) Find the vertical asymptotes of the graph of g o f (3:), if any. You need to prove that they are indeed asymptotes
