Question

9. U = R -2 -1 0 1 2 3 4
A = {x ( R | -2 ( x ( 1}
-2 -1 0 1 2 3 4
B = {x ( R | -1 < x < 3}

A(B = {x ( R | -2 ( x <3}
A(B = {x ( R | -1 < x ( 1}
Ac = {x ( R | x<-2 or x > 1}
Bc = {x ( R | x(-1 or x ( 3}
Ac(Bc = {x ( R | x < -2 or x (3}
Ac(Bc = Ac = {x ( R | x(-1 or x > 1}
(A(B)c = {x ( R | x(-1 or x > 1}
(A(B)c = {x ( R | x < -2 or x (3}


10. RQ Z
Za) Z+ ( Q TRUE
b) R- ( Q FALSE ( -(2 ( R- but -(2(Q)
c) Q ( Z FALSE (½ ( Q but ½ ( Z)
d) Z-(Z+ = Z FALSE (0(Z but 0( Z- and 0( Z+)
e) Q(R = Q TRUE
f) Q(Z = Q TRUE
g) Z+(R = Z+ TRUE
h) Z(Q = Z FALSE (½ ( Z, Z(Q = Q)​

Answer 1

Step-by-step explanation:

A(B = {x(R | -2 ( x < 3}

10. g ). Z + ( R = Z + TRUE
