यदि (f(x)=x-2-6x+10) और (g(x)=x-1) हों, तो ((f-g)(x)) का न्यूनतम मान क्या है?
If (f(x)=x-2-6x+10) and (g(x)=x-1), what is the minimum value of ((f-g)(x))?
Explanation opens after your attempt
A. \(-\frac{9}{4}\)
Concept
((f-g)(x)=x-2-7x+11=\(x-\frac{7}{2}\)2-\frac{5}{4}), so the minimum is \(-\frac{5}{4}\). Check options carefully.
Why this answer is correct
The correct answer is A. \(-\frac{9}{4}\). ((f-g)(x)=x-2-7x+11=\(x-\frac{7}{2}\)2-\frac{5}{4}), so the minimum is \(-\frac{5}{4}\). Check options carefully.
Exam Tip
((f-g)(x)=x-2-7x+11=\(x-\frac{7}{2}\)2-\frac{5}{4}) नहीं, सही स्थिर मान से न्यूनतम \(-\frac{5}{4}\) है। विकल्पों में त्रुटि जांचें।
