Question

Poate sa ma ajute cineva va rog e urgent! ​

Answer 1

c -3 < x-1 < 3 /+1

-2 < x < 4

x apartine (-2, 4)

C ={-1, 0, 1,2,3}

d -18 < x </ 2 , x apartine (-18, 2]

de unde x divizibil cu 2 => D={-18, -16, -14, -12, -10, -8, -6, -4, -2, 0, 2}

e -19 < 2x-1 < 19 /+1

-18< 2x < 20 /:2

-6 < x < 10 , x apartine (-6, 10)

dar -3 | x => E={-6, -3, -1, 1, 3, 6, 9}
