Let f(x) be a differentiable function and f^ (4)=5 . Then, _ x 2 f(4) - f (x² ) x-2 equals

Options

  1. A0
  2. B5
  3. C20
  4. D-20

Correct answer

D. -20

Step-by-step solution

Given, f^ (4)=5 array ll Now, _ x 2 f(4)-f (x² ) x-2 & [ 0 0 form ] = _ x 2 0-f^ (x² ) 2 x 1 = -f^ (4) 2 2 1 =-(5) 4=-20 array
