Question

The equation of parabola with vertex at origin the axis is along x-axis and passing through the point (2, 3) is
(a) y² = 9x
(b) y² = 9x/2
(c) y² = 2x
(b) y² = 2x/9​

Answer 1

$hello$

A parabola with its axis along the x-axis and vertex(0,0) and directrix x=-a,

has the equation:

y²=4ax

∵ (2,3) lies on the parabola,

3²=4a(2)

9=8a

9/2= 4a

∴ equation of parabola is :

y²=(9/2)x

a. y2= 9x/2

I hope my answer helps you....✌
