Question

Cine ma poate ajuta???

Answer 1

a)  x∈(-5;2)  b) x∈[13/2;28/3) c) x∈(-4/5;1] d) x∈[-2/3;2]

Aproximativ:
              AXA: -----------------------(-1,5)--(-0,8)-0-0,(6)-1--2---------6,5-----9,3--------

Answer 2

A={x apartine R / -5<x<2} = ( -5;2)
B={x apartine R / 13 supra 2 ≤x<28 supra 3 } = [13 supra 2 ; 28supra 3)
c={x apartine R/ - 4 supra 5<x≤1} = (- 4 supra 5 ; 1]
D={x apartine R / - 2 supra 3≤x≤2} =[-2supra3 ; 2]

atat sper sa te fi ajutat
