Modulus of x-a is continuous at x=a but not differentiable

This page will discuss the continuity and differentiability of the absolute value of $x-a$, that is, of the function $|x-a|$, at the point $x=a$. Note that the function $|x-a|$ is defined as follows: $|x-a| = x-a$ if $x\geq a$ $=-(x-a)$ if $x<a$ Continuity of |x-a| at x=a Let us now discuss the continuity of the … Read more
