Question

Urgent help. Please.

What is an equation of a parabola with the given vertex and focus?

Answer 1

The distance from the vertex to the focus is p

Answer 2

(x-h)^2=4p(y-k)
(h,k) is the vertex

Answer 3

so the equation would be:

(x+2)^2=4p(y-5) ?

Answer 4

you need to find p

Answer 5

Can you show me how?

Answer 6

As I posted previously:
The distance from the vertex to the focus is p

Answer 7

So p would equal 1?

Answer 8

yes
