A) a circle
B) a straight line
C) a parabola
D) a hyperbola
Correct Answer: A
Solution :
[a] \[\left| z \right|=1,\,\,let\text{ }\alpha =-1+3z\] \[\Rightarrow a+1=3z\] \[\Rightarrow \left| a+1 \right|=3\left| z \right|=3\] Hence, a lies on a circle centered at -1 and radius equal to 3.You need to login to perform this action.
