A) (?4, ?2) and (4, 2)
B) (4, ?2) and (?4, 2)
C) (?4, ?2) and (4, ?2)
D) (4, 2) and (?4, 2)
Correct Answer: C
Solution :
\[{{x}^{2}}=-8y\]Þ \[a=-2\]. So, focus \[=(0,-2)\] Ends of latus rectum \[=(4,-2),\,(-4,-2)\]. Trick : Since the ends of latus rectum lie on parabola, so only points \[(-4,-2)\]and \[(4,-2)\]satisfy the parabola.You need to login to perform this action.
