What help do you want? You are told exactly what to do and no one can do it for you. There are no "answers" to give. Just graph as you are told and look at the graphs.
I have attached the graphs for you. In the graph which the h values are varied, the topmost curve corresponds to h=0 then h=1 etc. Similarly in the graph which the k values are varied, the topmost curve represents the situation where k=0 then k=1 etc.
Hope this will help you.
Thread closed (you can discuss the matter with me via pm if the situation happens to be different to what I think it is).
