Which option correctly shows (-3\le x<0) on the number line?

Answer and explanation

Correct answer: \([-3,0)\)

In \(-3\le x<0\), \(-3\) has \(\le\), so it is included and is shown by a closed dot on the number line. Zero has \(<\), so it is excluded and is shown by an open dot. Hence, the interval is \([-3,0)\). Option A incorrectly excludes \(-3\) as well. Exam tip: use a square bracket for \(\le\) or \(\ge\), and a round bracket for \(<\) or \(>\).
