Question
Please do it in this way the way that I started and also make it lead to way where I can plot a simple graph
In the Gauss plane, the set
ze C: 12+1-il <√2, Rez+ Imz ≤0}
a) contains
point only
b) contains the half-line of negative real numbers
c) is a half-disk that intersects the set of strictly real numbers
d) is a half-disk that intersects the set B = {ZEC: 2=ly with y>0}
e) is a disk
one
How I'm solving it
2=x+ly
√x+iy+1-i ≤2
then I get lost
