Graph of a Set of Complex Numbers satisfying a Particular Condition

49 Views Asked by At

What would be the graph of the following set:

$$\{z \in \mathbb{C} \mid |z-1|\lt |z|\}$$

I tried out writing $z$ as $x+iy$, squaring both sides and ultimately came up with the condition on $x$ as $x \lt \frac{1}{2}$.

Help me judge where I am wrong and correct me. Thanks

$(x-1)^2+y^2 < x^2+y^2\\\Rightarrow -2x+1<0\\\Rightarrow 2x>1 \\\Rightarrow x > \frac{1}{2}$
