The domain is the set of first components of the ordered pairs, so ( {1,2,3} ) is correct. In exams, look at the first entries.
Step 2
Why this answer is correct
The correct answer is B. ( {1,2,3} ). The domain is the set of first components of the ordered pairs, so ( {1,2,3} ) is correct. In exams, look at the first entries.
Step 3
Exam Tip
प्रांत ordered pairs के पहले घटकों का समुच्चय होता है, इसलिए ( {1,2,3} ) सही है। परीक्षा में पहले स्थान वाले अवयव देखें।
The first component must be greater than some smaller (b), so (2,3,4) appear. (1) is not greater than any \(b\in A\).
Step 2
Why this answer is correct
The correct answer is B. ( {2,3,4} ). The first component must be greater than some smaller (b), so (2,3,4) appear. (1) is not greater than any \(b\in A\).
Step 3
Exam Tip
पहला घटक ऐसा होना चाहिए जो किसी छोटे (b) से बड़ा हो, इसलिए (2,3,4) आते हैं। (1) किसी भी \(b\in A\) से बड़ा नहीं है।
The second component must have some greater \(a\in A\), so (1,2,3) appear. There is no element in (A) greater than (4).
Step 2
Why this answer is correct
The correct answer is A. ( {1,2,3} ). The second component must have some greater \(a\in A\), so (1,2,3) appear. There is no element in (A) greater than (4).
Step 3
Exam Tip
दूसरा घटक ऐसा होना चाहिए जिससे बड़ा कोई \(a\in A\) मिले, इसलिए (1,2,3) आते हैं। (4) से बड़ा कोई अवयव (A) में नहीं है।
A. प्रांत ( {1,2,3} ), परिसर ( {4,5,6} )/Domain ( {1,2,3} ), range ( {4,5,6} )
Step 1
Concept
The domain is formed from first components and the range from second components. Therefore domain is ( {1,2,3} ) and range is ( {4,5,6} ).
Step 2
Why this answer is correct
The correct answer is A. प्रांत ( {1,2,3} ), परिसर ( {4,5,6} ) / Domain ( {1,2,3} ), range ( {4,5,6} ). The domain is formed from first components and the range from second components. Therefore domain is ( {1,2,3} ) and range is ( {4,5,6} ).
Step 3
Exam Tip
प्रांत पहले घटक और परिसर दूसरे घटक से बनता है। इसलिए domain ( {1,2,3} ) और range ( {4,5,6} ) हैं।
The condition gives pairs ( (3,2),(4,3),(5,4) ), so the domain is ( {3,4,5} ). In exams, take first components for domain.
Step 2
Why this answer is correct
The correct answer is B. ( {3,4,5} ). The condition gives pairs ( (3,2),(4,3),(5,4) ), so the domain is ( {3,4,5} ). In exams, take first components for domain.
Step 3
Exam Tip
शर्त से युग्म ( (3,2),(4,3),(5,4) ) बनते हैं, इसलिए प्रांत ( {3,4,5} ) है। परीक्षा में domain के लिए पहले घटक लें।
