Consider a two-player game with the following strategy spaces: S1 = [0, 5] and S2 = [0, 5]. Suppose the players' best-response functions, s1 = BR1(s2) and s2 = BR2(s1), are as pictured here
(a) Does this game have any Nash equilibria? If so, what are they?
(b) What is the set of rationalizable strategy profiles for this game?
