Best ResponseYou've already chosen the best response.1that the line must contiously go and still be a function (one to one) =P if that's what you mean

Best ResponseYou've already chosen the best response.1i meant, if f(x) is continuous, at x=0, \[\lim \limits{x \rightarrow 0^} f(x)=\lim \limits{x \rightarrow 0^+f(x)}\]

Best ResponseYou've already chosen the best response.1for x>0 , since x<0, select k cos x and put x=0 for x>0+ , since x>0, select 10e^xk and put x=0

Best ResponseYou've already chosen the best response.1when x>0, lim kcos x = k cos 0 = k when x>0+, lim 10e^xk = 10e^0k =10 k for continuity k=10k can you find k from here ?

Best ResponseYou've already chosen the best response.1just add k to both sides.
