Question

Let A = { 4 , 5 ,  6 , 7 , 8}  and B = { 2 , 6 , 8}. Draw the arrow diagrams for P and Q such that the relationship follows : (x,y)∈P   means that    x≤ y 

Answer 1

Hi SAM,

I have seen your question unanswered for a long time, so I will respond to what you have given in what appears to be an incompletely stated question.

Assume x € A and y € B.
Elements of P include (4,6) (4,8) (5,6) (5,8) (6,6) (6,8) (7,8) (8,8)
No arrow diagrams exist between P and Q since Q is undefined in the question!
