pls explain

Consider the following simultaneous-move game and answer the following questions Player B L R U 9, 10 ' 7, 5 Player A D 10, 2 8, 4 Find and draw the players' best response functions. Show all Nash equilibria on the same diagram. (4 marks) Suppose the game is changed to a sequential game where player A plays first and player B plays after observing A's move. Draw the game tree and find both subgame perfect equilibrium and Nash equilibria of the game. Compare these two types of equilibria. (5 marks) Suppose that the simultaneous-move game above is played repeatedly to infinity. Will the players be able to cooperate for higher payoffs compared to when the game is played once? Discuss in details. (7 marks)
