This exercise asks to determine the values of x for which the following function do not have derivative:(adsbygoogle = window.adsbygoogle || []).push({});

1. f(x) = |x - 1|

2. f(x) = |x^{2}- 2x|

I draw the functions and saw which were the points that had an derivative in the right different from the one in the left. For those were the points of the function that do not have derivative. But there isn't another way to solve it? I came across that those points were the roots of the functions.
