JEE Mains · Maths · STD 12 - 6. Application of derivatives

यदि अंतराल \([-3,0]\) में फलन \(f(x)=\left(x^2-2 x+7\right) e^{\left(4 x^3-12 x^2-180 x+31\right)}\) का निरपेक्ष उच्चतम मान \(f (\alpha)\) है, तो :

  1. A \(\alpha=0\)
  2. B \(\alpha=-3\)
  3. C \(\alpha \in(-1,0)\)
  4. D \(\alpha \in(-3,-1)\)
Verified Solution

Answer & Solution

Correct Answer

(B) \(\alpha=-3\)

Step-by-step Solution

Detailed explanation

\(f^{\prime}(x)=e^{\left(4 x^{2}-12 x^{2}-180 x+31\right)}(12\left(x^{2}-2 x+7\right)\) \((x+3)(x-5)+2(x-1)\) for \(x \in[-3,0]\) \(f ^{\prime}( x )<0\) \(f ( x )\) is decreasing function on \([-3,0]\) The absolute maximum value of the function \(f(x)\) is at \(x=-3\)…
