Question

Write the equation of a parabola with a vertex at (0, 0) and a focus at (0. -5).

Answer 1

this question is something like this:
Since vertex is the origin O(0,0)

and focus is on the X-axis,

the equation of this parabola is y² = 4px. ... (1)

Its focus is S ≡ ( p, 0 ) ≡ ( - 4, 0 ).

∴ p = -4

∴ 4p = 4( - 4 ) = -16

∴ equation of this parabola is : y² = -16x ......... Ans.
