Question

2. Efectuați:
a) (-3; 5) (2; 8); b) (-3; 7] [-4; 5); c)(-3; 2) [2; 5);
d) (-1;3] (3;6); e) (-00; 3) (-2; 5); f) (-3; +0) (-5; 1).

Answer 1

Răspuns:

a) = {-2,-1,0,1,2,3,4,5,6,7} sau = (-3,8)

b) = {-4,-3,-2,-1,0,1,2,3,4,5,6,7} sau = [-4,7]

c) = {-2,-1,0,1,2,3,4} sau = (-3,5)

d) = {-1,0,1,2,3,4,5} sau = [-1,6)

e) = {-infinit,0,1,2,3,4,5}. Sau. = (-infinit, 5]

f) = {-4,-3,-2,-1,+infinit}. Sau = (-5,+infinit)
