y+9=(x-4)^2

K U may need to make a account or stop putting ur name cause im pretty sure ppl dont need to know ur name.

Omggoshh. Please calm down. I just want some help in math.

K but ppl dont need to know ur name

Okay.

(4, -9)

Hayley.....  Actually, Melody has encouraged people to sign their names if they are posting as guests ... so no worries!

I get the vertex as   4 , -9     

  Did you try the graphing function of the calculator so you can look at it?

Do you mind me asking how you got that answer? just so i know how to do it next time. please and thank you! and i have not graphed it yet :) i always siggn my name at the bottom, and this girl keeps going off on me >:(

y + 9  =  (x - 4)^2

You have the x coordinate correct

Put it in this form, Hayley

y  = (x - h)^2  +  k

So we have.......  [subtracting 9 from both sides]

y = (x - 4)^ - 9

In this form.....the vertex can be read thusly, as  ....      (4 , -9)

In other words......the x coordinate of the vertex is the x value that makes x - 4  = 0  [this is 4[......   and the y coordinate  is just the last term and its associated sign.......

Knowing this, Hayley.....can you find the vertex of

y - 8 =  (x + 3)^2          ????

Awee C-r-a-p. i have to do the work! ok, one moment please
