Consider the parabola y^2+2 x+2 y-3=0 and match the items of List-I with those of the List-II. The correct match is A B C D
Options
- Aarray llll III & II & IV & I array
- Barray llll V & I & IV & II array
- Carray llll III & II & V & I array
- Darray llll IV & I & III & II array
Correct answer
A. array llll III & II & IV & I array
Step-by-step solution
We have, equation of parabola is array ll & y^2+2 x+2 y-3=0 & (y+1)^2-1+2 x-3=0 & (y+1)^2=4-2 x (y+1)^2=-2(x-2) & Vertex =(2,-1) array Axis : y+1=0 Focus : (-a+2,-1)= (- 1 2 +2,-1 )= ( 3 2 ,-1 ) Directrix : x-2= 1 2 x= 5 2 2 x-5=0
