Why this answer is correct
The correct answer is A. (-2) से (6) तक छायांकन और (3) पर खाली वृत्त / Shading from (-2) to (6) with an open circle at (3). The notation \(\setminus{3}\) means remove (3). So an open circle appears at (3) inside the closed interval.
Exam Tip
\(\setminus{3}\) का अर्थ है (3) को हटाना। इसलिए बंद अंतराल में (3) पर खाली वृत्त दिखेगा।
