यदि (f(x)=2x+1) और डोमेन ((-2,3]) है, तो रेंज क्या होगी?
If (f(x)=2x+1) and the domain is ((-2,3]), what is the range?
Explanation opens after your attempt
A. ((-3,7])
Concept
(2x+1) is an increasing linear function, so the endpoints become (-3) and (7). In exams keep an open endpoint open.
Why this answer is correct
The correct answer is A. ((-3,7]). (2x+1) is an increasing linear function, so the endpoints become (-3) and (7). In exams keep an open endpoint open.
Exam Tip
(2x+1) बढ़ता हुआ रेखीय फलन है, इसलिए endpoints (-3) और (7) बनते हैं। परीक्षा में खुले endpoint को खुला ही रखें।
