Question

A parabola can be drawn given a focus of (1,3) and a directrix of x = -7. What

can be said about the parabola?
The parabola has a vertex at (
), has a p-value of
and it


PLEASE HELP

Answer 1

The parabola has a vertex at (-3, -6), has a p-value of 4 and it opens right.

Explanation:

Answer 2

Below.

Explanation:

The parabola will open to the right and will be symmetrical about y = 3.

The vertex is halfway between x = 1 and x = -7 making it at (-3, 3).

The p value is the distance between the vertex and the focus - here it is 1 - -3

= 4.
