The interval in which (y= ( (x)), x>1 ) is decreasing is

Options

  1. A((- , 0) (2, ) )
  2. B((0,2) )
  3. C((0,1) )
  4. DNone of the above

Correct answer

D. None of the above

Step-by-step solution

Given function (y=l( (x)), x > 1 ) ( d y d x = 1 x x , x > 1 ) ( y ) is a decreasing, then ( d y d x 1 x 1 ) ( x ), for decreasing
