Show a function cannot be the derivative of an entire function (complex analysis)
$begingroup$
Suppose we are given two complex integrals along contours both $4overline{z}$ with paths.
I would like to know how to prove the function $f(z)=4overline{z}$ cannot be the derivative of an entire function.
How would I go about proving this using the two integrals of $4overline{z}$ I calculated originally?
Thank you very much.

I suppose that (z bar) is $bar z$, the complex conjugate of $z$. Do you know that this is not an analytic function?
