Answer: $z$

Hint: [r] is not continuous ⇒ not differentiable at every point.

If $\mathrm{f}(\mathrm{x})=\mathrm{f}_{1}(\mathrm{x})+\mathrm{f}_{2}(\mathrm{x})$ where $\mathrm{f}_{1}(\mathrm{x})$ is differentiable at $x=C$ and $\mathrm{f}_{2}(\mathrm{x})$ is not differentiable at $x=C$ then $\mathrm{f}(\mathrm{x})=\mathrm{f}_{1}(\mathrm{x})+\mathrm{f}_{2}(\mathrm{x})$ is also not differentiable at $x=c.$
