यदि (f(x)=2x-1) और (g(x)=3-x) हैं, तो ((2f-3g)(4)) का सही मान चुनिए।

If (f(x)=2x-1) and (g(x)=3-x), choose the correct value of ((2f-3g)(4)).

Explanation opens after your attempt
Correct Answer

A. (17)

Step 1

Concept

((2f-3g)(x)=4x-2-9+3x=7x-11), hence ((2f-3g)(4)=17). In linear combinations, pay close attention to signs.

Step 2

Why this answer is correct

The correct answer is A. (17). ((2f-3g)(x)=4x-2-9+3x=7x-11), hence ((2f-3g)(4)=17). In linear combinations, pay close attention to signs.

Step 3

Exam Tip

((2f-3g)(x)=4x-2-9+3x=7x-11), इसलिए ((2f-3g)(4)=17)। रैखिक संयोजन में चिह्नों पर विशेष ध्यान दें।
