Question

Dados los siguientes intervalos: A = {x ∈ R/ 5 ≤x < 9}, B = {x ∈ R/ 4 < x ≤7}, C = {x ∈ R/ x ≥8}Determina ( A ∩ B ) – C​

Answer 1

Explicación paso a paso:

A = {x ∈ R/ 5 ≤x < 9}

A={5,6,7,8}

B = {x ∈ R/ 4 < x ≤7}

B = {5,6,7}

C = {x ∈ R/ x ≥8}

C = {8,9,10,11...}

( A ∩ B ) – C={5,6,7}-C

( A ∩ B ) – C={5,6,7}
