यदि (f(x)=2x-1), (g(x)=x+3) और (\(\lambda f+g\)(1)=9), तो \(\lambda\) क्या है?
If (f(x)=2x-1), (g(x)=x+3), and (\(\lambda f+g\)(1)=9), what is \(\lambda\)?
Explanation opens after your attempt
A. (5)
Concept
(f(1)=1) and (g(1)=4), so \(\lambda+4=9\) and \(\lambda=5\). In a linear combination, first find the function values.
Why this answer is correct
The correct answer is A. (5). (f(1)=1) and (g(1)=4), so \(\lambda+4=9\) and \(\lambda=5\). In a linear combination, first find the function values.
Exam Tip
(f(1)=1) और (g(1)=4), इसलिए \(\lambda+4=9\) और \(\lambda=5\)। रैखिक संयोजन में पहले फलन मान निकालें।
