Which option is the combined solution of (x>2) and (x\leq 9)?कौन सा विकल्प (x>2) और (x\leq 9) का संयुक्त हल है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: ((2,9])((2,9])
Taking both conditions together gives (2<x\leq 9). Use an open endpoint for a strict sign and a closed endpoint for equality.दोनों शर्तों को साथ लेने पर (2<x\leq 9) मिलता है। सख्त चिन्ह पर खुला सिरा और बराबरी वाले चिन्ह पर बंद सिरा रखें।
