i am given two differentiable function f and g .

prove that for u(x)=max(f(x),g(x))

and v(x)=min(f(x),g(x))

there is one sided derivatives

??

deffentiable function is a function which on soome point its

left side derivative equals its write side derivative.

so

if both functions are derivatable.

then it doent matter what function we take

there for sure will be a function where

it has a point for which there is a derivative on both sides

even though we need only one.

so its an over kill

am i correct?
