 Sa se reprezinte grafic in plan: A x B , B x A, A x A, Bx B, daca:

  a) A= [1,3] ; B= { 1,2,4}

  b) A= [-1,3]; B= [1,2]

Răspuns :

a)AXB={(1,1),(1,2),(1,4),(3,1),(3,2),(3,4)}
BXA={(1,1),(1,3),(2,1),(2,3), (4,1),(4,3)}
AXA={(1,1),(1,3),(3,1),(3,3)}
BXB={(1,1),(1,2),(1,4),(2,1),(2,2),(2,4),(4,1),(4,2),(4,4)}
b)
AXB={(-1,1),(-1,2),(3,1),(3,2)}
BXA={(1,-1),(1,3),(2,-1), (2,3)}
AXA={(-1,-1,), (-1,3),(3,(-1),(3,3)}
BXB={(1,1),(1,2),(2,1),(2,2)}
SI LE REPREZINTI GRAFIC
