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
Correct Answer

A. ((-3,7])

Step 1

Concept

(2x+1) is an increasing linear function, so the endpoints become (-3) and (7). In exams keep an open endpoint open.

Step 2

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.

Step 3

Exam Tip

(2x+1) बढ़ता हुआ रेखीय फलन है, इसलिए endpoints (-3) और (7) बनते हैं। परीक्षा में खुले endpoint को खुला ही रखें।
