# Write the following intervals in set-builder form :(iv) $[-23,5]$

$\begin{array}{1 1}(A)\;\{x : x\in R,-23 \leq x < 5\}\\(B)\;\{x : x\in R,-23 \geq x < 5\}\\(C)\;\{x : x\in R,-20 \leq x < 5\}\\(D)\;\{x : x\in R,-18 \leq x < 5\}\end{array}$

$\{x : x\in R,-23 \leq x < 5\}$
Hence (A) is the correct answer.
