A) \[-1\]
B) \[x=1\]
C) \[x=-3/2\]
D) \[x=3/2\]
Correct Answer: D
Solution :
Given equation can be rewritten as \[{{(y+2)}^{2}}=-4\left( x-\frac{1}{2} \right)\] \[\Rightarrow \] s\[{{Y}^{2}}=-4X,\] where \[Y=y+2\] and \[X=x-\frac{1}{2}\]. The equation of directrix is \[X=1\]. \[\therefore \] \[x-\frac{1}{2}=1\,\,\,\Rightarrow \,\,\,x=\frac{3}{2}\]You need to login to perform this action.
