यदि \(x\in[-3,2\)) है, तो (4-2x) किस अंतराल में होगा?

If \(x\in[-3,2\)), in which interval will (4-2x) lie?

Explanation opens after your attempt
Correct Answer

A. ((0,10])

Step 1

Concept

Multiplying by (-2) reverses the order, and then (4) is added. Therefore (4-2x\in(0,10]).

Step 2

Why this answer is correct

The correct answer is A. ((0,10]). Multiplying by (-2) reverses the order, and then (4) is added. Therefore (4-2x\in(0,10]).

Step 3

Exam Tip

(-2) से गुणा करने पर क्रम उलटता है और फिर (4) जोड़ते हैं। इसलिए (4-2x\in(0,10]) होगा।
