Question
This is how I solved it but I don’t know which option to pick just because I don’t understand them could you please help me out there
![In the Gauss plane, the set:
{26:12+1-ilsva, Rez+ Im z zo]
a) is a half-disk that intersects the set of strictly negative real numbers.
b) contains the set B = {2E &: 2 = iy, with y20}
c) is a disk
d) contains one point only
e) is a half-disk that intersects the set B = {2 € 6:2=iy, with y>0}
how I solved it
z: a+ib
la+ib+1-il≤√2
√(a+1)² +i(b-1)² ≤ VZ
(a+1)²+i(b-1)² ≤2
C:-1,1
R: 2
