First of all g(x) is defined on [c,b] such that it is continuous on [b,c] and differentiable on [b,c].since f(x) is also continuous on [a,c] and differentiable on (a,c). Therefore ,for differentiability of h(x) at x=c is that it must be continuous at x=c and left hand derivative of h(x) at x=c must be equal to right hand derivative of h(x) at x=c.it mean that f'(c)= g'(c).
Hence the necessary and sufficient condition for differentiablity of h(x) is h'(c)=0 , i.e. f'(c)=h'(c)
