Question

Which of the following sets are equal? A = {: 2 − 4 + 3 = 0}, B = {: 2 − 3 + 2 = 0}, C = {: ∈ , < 3}, D = {: ∈ , , < 5}, E = {1,2}, G = {3,1}, H = {1,1,3}, F = {1,2,1}.

Answer 1

Answer:

A = {: 2 − 4 + 3 = 0}, B = {: 2 − 3 + 2 = 0}, C = {: ∈ , < 3}, D = {: ∈ , , < 5}, E = {1,2}, G = {3,1}, H = {1,1,3}, F = {1,2,1}.

Answer 2

Answer:

A = {0, 1, 2}

B = {x ∈ R | -1 ≤ x < 3}

C = {x ∈ R | -1 < x < 3}

D = {x ∈ Z | -1 ≤ x < 3}

E = {x ∈ Z+ | -1 ≤ x < 3}
