The following can be written in interval as :

(i) {x : x $\in$ R, – 4 $<$ x $\leq$ 6} $= \left ( -4 ,6 \right ]$

(ii) {x : x $\in$ R, – 12 $<$ x $<$ –10} $= \left ( -12,-10 \right )$

(iii) {x : x $\in$ R, 0 $\leq$ x $<$ 7} $= \left \left [ 0,7\right )$

(iv) (iv) {x : x $\in$ R, 3 $\leq$ x $\leq$ 4} $=\left [ 3,4 \right ]$
