Question

Dados os conjuntos A = ( -2 , -1 , 0 , 1 , 2 ) , B = ( 0 , 1 , 2 , 3 ) e C = ( -1 , 0 , 4 , 7 ) , determine a) AUB b ) A^B c ) AUC d ) BUC e ) A ^C f ) B ^ C

Answer 1

a) AUB = {-2,-1,0,1,2,3}; b) A∩B = {0,1,2} ; c) AUC = {-2,-1,0,1,2,4,7}; d) BUC = {-1,0,1,2,3,4,7}; e) A∩C = {-1,0}; f) B∩C = {0}
