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
Correct Answer

A. (5)

Step 1

Concept

(f(1)=1) and (g(1)=4), so \(\lambda+4=9\) and \(\lambda=5\). In a linear combination, first find the function values.

Step 2

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.

Step 3

Exam Tip

(f(1)=1) और (g(1)=4), इसलिए \(\lambda+4=9\) और \(\lambda=5\)। रैखिक संयोजन में पहले फलन मान निकालें।
