If the number line has a closed dot at (-8) and shading to the right, what is the interval notation?यदि संख्या रेखा पर (-8) पर बंद बिंदु है और दाईं ओर छायांकन है, तो interval notation क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: ([-8,\infty))([-8,\infty))
The closed dot includes (-8), and right shading means (x\ge -8). In exams, read a right ray as the greater side.बंद बिंदु (-8) को शामिल करता है और दाईं ओर shading (x\ge -8) बताती है। परीक्षा में right ray को greater side समझें।
