The derivative of f( x) w.r.t. g( x) at x= 4 , where f^ (1)=2 and g^ ( 2 )=4 is

Options

  1. A1 2
  2. B2
  3. C2
  4. D1 2

Correct answer

A. 1 2

Step-by-step solution

array l d d x f( x) d d x g( x) = f^ ( x) ² x g^ ( x) x x At x= 4 we get = f^ ( 4 ) ( ² 4 ) g^ ( 4 ) 4 4 = f^ (1)(2) g^ ( 2 )( 2 )(1) = 2 2 4 2 = 1 2 array
