The coordinates of the end point of the latus rectum
of the parabola (y1)2=2(x+2) which does not
lie on the line 2x + y + 3 = 0 are

a
(– 2, 1)
b
(– 3/2, 1)
c
(– 3/2, 2)
d
(– 3/2, 0)

detailed solution

Correct option is C

Y2=4AX where Y=y−1,X=x+2,A=1/2. End of the L.R. is (X=A,Y=±2A)=(−3/2,2)or (– 3/2, 0) but (– 3/2, 0) lies on the line.
