Question:
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) $F=(0,5]$
Solution:
(i) $A=\{x: x \in R,-2 (ii) $B=\{x: x \in R, 4 \leq x \leq 10\}$ (iii) $C=\{x: x \in R,-1 \leq x<8\}$ (iv) $D=\{x: x \in R, 4 (v) $E=\{x: x \in R,-10 \leq x<0\}$ (vi) $F=\{x: x \in R, 0
