Questions
The equation of the parabola having vertex at origin and focus at
a
y2=24x
b
x2=12y
c
x2=-12y
d
y2=12x
detailed solution
Correct option is D
Given vertex is at origin, and the focus is 23,0Since the vertex of the parabola is 0,0 and the focus lies on the positive x - axis. the x- axis is the axis of the parabola while the equation of the parabola is of the form y2=4ax since the focus is 3,0, a=3Therefore, the equation of the parabola is y2=12xTalk to our academic expert!
