Let a function

y = y\left( x \right)

be defined parametrically by

x = 2t - \left| t \right|,y = {t^2} + t\left| t \right|

. Then,

y'\left( x \right),x > 0

View answer and explanation

Correct option: D

Does not exist

Option D (Does not exist) is correct because the derivative does not exist at x=0 due to different limits from the left and right.
