Write each of the following intervals in the set-builder from: (i) A = (–2, 3) (ii) B = [4, 10] (iii) C = [–1, 8) (iv) D = (4, 9] (v) E = [–10, 0) (vi) F = (0, 5]

Answer»

(i) A = {x : x ϵR, –2 < x < 3}

(ii) B = {x : x ϵ R, 4 ≤ x ≤ 10}

(iii) C= {x : x ϵ R, –1 ≤ x < 8}

(iv) D = {x : x ϵ R, 4 < x ≤ 9}

(v) E = {x : x ϵ R, –10 ≤ x < 0}

(vi) F = {x : x ϵ R, 0 < x ≤ 5}
