DERIVATIVE OF ABSOLUTE VALUE FUNCTION. Let |f (x)| be an absolute value function. Then the formula to find the derivative of |f (x)| is given below. Based on the formula given, let us find the derivative of |x|. |x|' = (ˣ⁄|ₓ|)(x)' |x|' = (ˣ⁄|ₓ|)(1) |x|' = ˣ⁄|ₓ|. Therefore, the derivative of |x| is ˣ⁄|ₓ|. Let y = |x|'. Then, we have y = ˣ⁄|ₓ|.

19 kwi 2021 · Let $\size x$ be the absolute value of $x$ for real $x$. Then: $\dfrac \d {\d x} \size x = \dfrac x {\size x}$ for $x \ne 0$. At $x = 0$, $\size x$ is not differentiable. Corollary. Let $u$ be a differentiable real function of $x$. Then: $\dfrac \d {\d x} \size u = \dfrac u {\size u} \dfrac {\d u} {\d x}$ for $u \ne 0$.

21 cze 2017 · First compare the graphs: $|x|$ $x|x|$ $|x|$ is very sharp at $(0,0)$, so it doesn't have a derivative there. $x|x|$ has derivatives because $x|x|$ is equal to: $\begin{cases}y=x^2 & x > 0\\y=0 & x = 0\\y=-x^2& x<0\end{cases}$ And "square" makes $y = x^2$ tangent same of the $y=-x^2$. Same tangents = differentiable. See those:
The general form of an absolute value function is f(x)=a|x-h|+k. From this form, we can draw graphs. This article reviews how to draw the graphs of absolute value functions.
