ZBIÓR LICZB RZECZYWISTYCH I JEGO PODZBIORY.
ROZWIĄŻ:
A) Ix+2I = 3
B) Ix-3I ≤ 2
C) Ix+3I > 1
Proszę o rozwiązanie:)
A) Ix+2I = 3x+2=3 i x+2=-3
x=1 i x=-5
x-3≤2 i x-3≥-2
x≤5 i x≥1
x∈<1,5>C) Ix+3I > 1
x+3>1 i x+3<-1
x>-2 i x<-4
x∈(-2,-4)
licze na naj
a)
Ix+2I=3
x+2=3 i x+2=-3
x=3-2 x=-3-2
x=1 x = -5
R=(1,-5)
b)
x-3<= 2 i x-3<= -2
x<=2+3 x<=-2+3
x<=5 x<=1
c)Ix+3I>1
x+3>1
