A) \[x=-1\]
B) \[x=1\]
C) \[x=-\frac{3}{2}\]
D) \[x=\frac{3}{2}\]
Correct Answer: D
Solution :
The equation of parabola as \[{{(y+2)}^{2}}=-4\left( x-\frac{1}{2} \right)\] Shifting the origin\[\left( \frac{1}{2},-2 \right),\]the equation of parabola becomes \[{{y}^{2}}=4X\] where \[X=x-\frac{1}{2},Y=y+2\] an equation of its directrix is\[X=1\]required directrix \[x=\frac{3}{2}\]You need to login to perform this action.
