Best ResponseYou've already chosen the best response.0k so u cant take log of a negative number .... its a property will be helpful to memorize it .... max x = 1

Best ResponseYou've already chosen the best response.0right..how would i solve with first order conditions?

Best ResponseYou've already chosen the best response.0it has no maximum value.. it goes to infinity as x goes to negative infinity

Best ResponseYou've already chosen the best response.0can you solve this with derivatives?

Best ResponseYou've already chosen the best response.0yeah the derivative of log(1x)=1/(1x) when you set it equal to zero, it has no solution.. therefore, there are no extreme values to the given function

Best ResponseYou've already chosen the best response.0i see that makes sense, however in a similar problem the answer says x = 0, i.e., choose x to maximize (y  x)

Best ResponseYou've already chosen the best response.0sorry the question is choose x to maximize log(yx)

Best ResponseYou've already chosen the best response.0are you sure about the answer? that it's x=0

anonymous

Best ResponseYou've already chosen the best response.0because I think negative values of x give greater values for the function log(yx) than x=0

Best ResponseYou've already chosen the best response.0oh i think they are assuming that x greater than or equal to zero

Best ResponseYou've already chosen the best response.0then i'm not sure how the derivate would yield x=0
