Question

1. what is an equation of the parabola with vertex at the origin and focus (-6 0)?

Answer 1

you know what this looks like?

Answer 2

i ask because you need that to start

Answer 3

hmmm. a graph??

Answer 4

yeah, the graph

Answer 5

looks like that
so you know
a) it opens to the left
b) the \(y\) term is squared

Answer 6

since the vertex is \((0,0)\) it is going to look like
\[y^2=-4px\] where \(p\) is the distance between the vertex and the origin
that distance is pretty clearly \(6\)

Answer 7

let me know when you get
\[y^2=-24x\]

Answer 8

we can check it if you like

Answer 9

yup
looks good to me

Answer 10

so it would be \[y= \frac{ 1 }{ 24} x^{2}\]

Answer 11

no

Answer 12

guess i was not clear

the \(y\) term is squared, not the \(x\) term

Answer 13

also there is a minus sign

Answer 14

WAIT SO ITS -24 Y^2

Answer 15

lol no

Answer 16

\[y^2=-24x\] really trust me

Answer 17

deng it. ugh i meant -1/24 y^2

i have answer choices

Answer 18

yeah, multiple choice
the death of clear thinking and mathematics
no matter, if you see
\[-\frac{1}{24}y^2=x\] go with that one

Answer 19

would the 1 be negative.

Answer 20

i don't know dear
a minus sign is a minus sign
it does not live in the top or the bottom of a fraction right?

Answer 21

because none of my answer choices have that. it's either positive 1 over 24 or negative 1 over 24

Answer 22

if you want to post your answer choices i will pick one out for you

Answer 23

go with \(\frac{-1}{24}\)

Answer 24

yeah that one seems right ^ thank you for being patient :D

Answer 25

which is i hope pretty clearly identical to \(-\frac{1}{24}\)

Answer 26

yw

Answer 27

you made me blush, i have to be patient
