Question

Find the standard form of the equation of the parabola with a focus at (3, 0) and a directrix at x = -3.

Answer 1

Dan, I needed help on my last question still :(

Answer 2

(6, 6)

Answer 3

x+3/y^2

Answer 4

9/36

oh 1/4

Answer 7

But tahts not one of my options dan! :( on the last Q it wasnt one of the options either

Answer 8

how?

Answer 9

y = +-4x + 12

Answer 10

But dannnn ... :(

Answer 11

y = (1/12)x^2

-12y = x^2

x = (1/12)y^2

y^2 = 6x

Answer 12

what do i do to our equation that turns it into one of those?

Answer 13

(3, -3)

Answer 14

well it goes all the way to -3

Answer 15

Darn it... :/ im sorry if i was confusing

Answer 16

start over, look up what a directrix means, give me a picture i can work with and ill tell you the formula

Answer 17

okay one sec please dont go anywhere

Answer 18

A parabola is defined as follows: For a given point, called the focus, and a given line not through the focus, called the directrix, a parabola is the locus of points such that the distance to the focus equals the distance to the directrix.
