Answer 1

if a f(x) is continous and differentiable in [a,b]
then there exist
f'(c) = f(b)- f(a)/b-a
where c€[a,b]

Answer 2

Hi friend,
Lagrange's mean value theorem-
Let f(x) be defined and continuous at all x in the closed interval [a,b] and diffrentiable at all x in open interval (a,b).There exists atleast one number c satisfying a<c<b such that f¹(c)=f(b)-f(a)/b-a.
  HOPE THIS HELPS...
