Questions
The equation of the parabola having focus at and directrix
a
y2=24x
b
y2=12x
c
y2=-24x
d
x2=-12y
detailed solution
Correct option is D
Focus 0,-3 and directrix y=3Since, the focus lies on the y-axis, it is the axis of parabolaAlso, the directrix y=3 in the above the x- axis, while the focus 0,-3i is below x- axishence, the parabola is of the form x2=4ay Here a = 3 Therefore, the equation of the required parabola is x2=12yTalk to our academic expert!
