Best ResponseYou've already chosen the best response.0but i have no idea how to graph one myself

Best ResponseYou've already chosen the best response.0i am assuming if I graphed this I could see the limit

Best ResponseYou've already chosen the best response.1If you were approaching from the right, [[x]] would be 4

Best ResponseYou've already chosen the best response.0yea how do i know to start at 0 and stop 1

Best ResponseYou've already chosen the best response.0then start at 1,2 and stop at 2,1

Best ResponseYou've already chosen the best response.1greatest integer function definition, [[x]] is the greatest integer less than or equal to x

Best ResponseYou've already chosen the best response.1f(x)=[[x]] f(3.999999999999999999999)=3 f(3)=3 f(4)=4

Best ResponseYou've already chosen the best response.0so by definition if x=1 then [[x]] is x>= 1

Best ResponseYou've already chosen the best response.1Just think of it as going down the steps instead of up...you'll start as close as you can to [[x]]+1 and end up at [[x]]

Best ResponseYou've already chosen the best response.1but you're not actually starting at [[x]] + 1

Best ResponseYou've already chosen the best response.0so if I were doing 5[[4]]7 i would plot from (4,13) t0 (5,13) with an open point at (5,13)?

rickjbr

Best ResponseYou've already chosen the best response.1yes, open circle at (5,13), closed at (4,13)

Best ResponseYou've already chosen the best response.0and if it happened to be [[x]] i would just reflect
