Since the limits from the right and left match, the overall limit is. Note that in this case, the limit at 2 does not match the function value at 2, so the function is discontinuous at this point, hence the function is nondifferentiable at this point as well. Apply and interpret the central limit theorem for averages. The limits are defined as the value that the function approaches as it goes to an x value.
