If |z|=2, then the points representing the complex numbers -1+5z will lie on a
Circle
Straight line
Parabola
None of these
Let ω=-1+5z, then ω+1=5z
⇒|ω+1|=5|z|=5*2=10
(∵|z|=2, Given vlaue)
Thus ω lies on a circle.
If |z| = 3, then the points representing the complex numbers −2+4z lie on a
If the Imaginary part of (2z+1)(iz+1) is -2, then the locus of the point representing z in the complex plane is:
