At  x=-1 it has a kink but to the left of x=1 u have x^2 applying for min value
 nd LHD is 2...to the right side u have 2x-1 applying for a min nd u have RHD as  2 again...so its differentiable
note that at x=1 line y=2x-1 is tangent to y = x^2 .so it doesnt result in a kink nd wot u get is a smooth differentiable line...i hope u got it:-)
