Best ResponseYou've already chosen the best response.0P'(x) is strictly increasing.. that doesnt help saying it wont cross 0...

Best ResponseYou've already chosen the best response.2not P'(x) but P(x) is strictly increasing (why?) and P(x) is continous ...so there are no local Max or Min but there is a one root
