what value for x f(x)=|2x-7| is not derivable. Share with your friends Share 9 Mayank answered this We have, fx=|2x-7| DIFFERENTIABILITY TEST AT x = 72 :LHD at x = 72 = limh→0f72-h - f72-h= limh→0272-h-7 - 0-h= limh→02h-h = -2RHD at x = 72 = limh→0f72+h - f72h= limh→0272+h-7 - 0h= limh→02hh = 2since, LHD≠RHD at x = 72So, fx is not differentiable at x = 72 12 View Full Answer Shogun answered this Derivative 2-0 2
