Homework Help: Complex Analysis - Sketching regions in a complex plane

  1. Mar 1, 2012 #1
    1. The problem statement, all variables and given/known data
    |2z -1|[itex]\geq[/itex]|z + i|

    3. The attempt at a solution
    The problem I have with this one is the 2z, I just need a clue on how to go about centering this one. If it were just |z - 1|; z[itex]_{0}[/itex] would be 1.
