A) \[{{y}^{2}}=8x\]
B) \[{{y}^{2}}=-8x\]
C) \[{{y}^{2}}=\sqrt{8}x\]
D) \[{{x}^{2}}=-8y\]
Correct Answer: D
Solution :
Since vertex is origin and directrix of parabola is\[y=2\] \[\therefore \] Focus\[a=-2\] \[\therefore \]Required equation of parabola is \[{{x}^{2}}=4\cdot 2\cdot y\] \[\Rightarrow \] \[{{x}^{2}}=-8y\]You need to login to perform this action.
