Question

A={X|X€Z,X<sau egal 3 si X> -4},B={X|X€Z,-3<X<sau egal 4calculati A U B,Aintersectat cu B,A\B​

Answer 1

Răspuns:

Explicație pas cu pas:

-4 < x ≤ 3

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

______

-3 < x ≤ 4

B = {-2, -1, 0, 1, 2, 3, 4}

_________

A U B = {-3, -2, -1, 0, 1, 2, 3, 4}

A ∩ B = {-2, -1, 0, 1, 2, 3}

A \ B = {-3}
