about to only mathematics

A

a pair of straing lines

B

circle

C

parabola

D

ellispe

Text Solution

Verified by Experts

The correct Answer is:
C
We have,
`|(x-2)+i(y-1)|=|z||(1)/(sqrt2)costheta-(1)/(sqrt2)sintheta|`
where `theta =arg z`.
`sqrt((x-2)^(2)+(y-1)^(2))=(1)/(sqrt2)|x-y|`,
which represents a parabola
