यदि (f(x)=5x-4) और डोमेन ((-3,2]) है, तो रेंज क्या होगी?

If (f(x)=5x-4) and the domain is ((-3,2]), what is the range?

Explanation opens after your attempt
Correct Answer

A. ((-19,6])

Step 1

Concept

(5x-4) is an increasing linear function. Since (x=-3) is open, (-19) is open, and (x=2) gives included (6).

Step 2

Why this answer is correct

The correct answer is A. ((-19,6]). (5x-4) is an increasing linear function. Since (x=-3) is open, (-19) is open, and (x=2) gives included (6).

Step 3

Exam Tip

(5x-4) बढ़ता हुआ रेखीय फलन है। (x=-3) खुला है इसलिए (-19) खुला और (x=2) से (6) शामिल है।
