Answer 2

Answer:

(i) {x : x ∈ R, -3 < x ≤ 5}

X= -2, -1, 0,1,2,3,4,5.

(ii) {x : x ∈ R, -5 < x < -1}

X= -4, -3, -2,

(iii) {x : x ∈ R, 2 ≤ x ≤ 7}

X=2, 3,4,5,6,7

(iv) {x : x ∈ R, 0 ≤ x < 3} .

X= 0,1,2

(v) {x:x ∈ R, X ≤ 5}

X=....... -2,-1,0,1,2,3,4,5

(vi) {x : x ∈ R, x < -3}.

X=....... -6, -5, -4

(vii) {x : x ∈ R, x ≥ -2}.

-2, -1, 0,1,2,3,4...........
