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
A. (17)
Concept
((2f-3g)(x)=4x-2-9+3x=7x-11), hence ((2f-3g)(4)=17). In linear combinations, pay close attention to signs.
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.
Exam Tip
((2f-3g)(x)=4x-2-9+3x=7x-11), इसलिए ((2f-3g)(4)=17)। रैखिक संयोजन में चिह्नों पर विशेष ध्यान दें।
