Question

Find the point where the function f(z) = (2+z)/2-z ceases to be analytic..​

Answer 1

Answer:

If you have some theorem, proposition, or lemma that the sum, difference, quotient, and product of analytic functions are analytic (except at points where the denominator is zero), then z2z−3 is analytic because the function z↦z is.
