Fujio Takata,

Perhaps the following code will work for you:

x[Condition[t_,t\[LessEqual]0]]=2
x[Condition[t_,t>0]]=a x[t-1](1-x[t-1])
Block[{a=2},Plot[x[t],{t,0,9}]]


On another note, can anyone explain why the following code blows up?

x[t_]=Piecewise[{{2,t<=0},{a x[t-1](1-x[t-1]),5>t>0}}]

Regards,
