Question

find the equation of the directrix and the axis of the parabola 3x2=8y​

Answer 1

1. 3 X 2 =8y
2. 6=8y
3. 6/8=y
4. 3/4=y

Answer 2

Answer:

${3x}^{2} = 8y$

We can write this as

${x}^{2} = \frac{8}{3}y = 4( \frac{2}{3})y$

Graph is in attachment.

Axis is y -axis=0

So, from this equation we get

$a = \frac{2}{3}$

on comparing with standard form,

${x}^{2} = 4ay \\ \\ \boxed{y = \frac{ - 2}{3}}$
