The question is to use the graph of $f$ to find is f differentiable or not on the given interval?
$f(x)=sqrt{4-x}$ following are the intervals $[0,4]$ and $[-5,0]$ and I have done this question as following
$f$ is differentiable:
functions derivatives

You missed a sign using ( or not using (?)) the chain rule, what did You think You proved and how is differentiability defined e.g. in the point $x=-4$ ( which is no interior point)....(Please use MathJax)

As the left hand limit is equal to right hand limit which proves that f exists so it can be stated that f is differentiable

$f$ exists, sure, but You didn't prove that, You proved that it is differentiable at $x=0$, though You missed a sign (Please use MathJax)
