Question

Wyznacz zbiory:A,B, AB, AB, A\B,B/A jezeli:

A={a: a E N i a7 } , B={b: b E C i -4<b3 }

Answer 1

A={a: a E N i a7 } , B={b: b E C i -4 < b 3 }

 

A = { 0, 1, 2, 3, 4, 5, 6, 7}

B = {-3, -2, -1, 0, 1, 2, 3 )

 

A ∨ B = {-3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7}

A ∧ B = {1, 2, 3 }

A \ B = {4, 5, 6, 7}

B \ A = {-3, -2, -1}
