**Write the following as intervals:**

**(i) {x: x ∈ R, -4 < x ≤ 6}**

**(ii) {x: x ∈ R, -12 < x < -10}**

(iii) {x: x ∈ R, 0 ≤ x < 7}

(iv) {x: x ∈ R, 3 ≤ x ≤ 4}

(iii) {x: x ∈ R, 0 ≤ x < 7}

(iv) {x: x ∈ R, 3 ≤ x ≤ 4}

Answer

(i) {x: x ∈ R, -4 < x ≤ 6} = (-4, 6]

(ii) {x: x ∈ R, -12 < x < -10} = (-12, -10)

(iii) {x: x ∈ R, 0 ≤ x < 7} = [0, 7)

(iv) {x: x ∈ R, 3 ≤ x ≤ 4} = [3, 4]
