Answer 1

I'm not so sure about this but maybe @pooja195 can help?

Answer 2

Mkay, thank you for at least looking at it :).

Answer 3

Oh no problem!

Answer 4

im not sure about this one either :/ maybe @Nnesha would know

Answer 5

Alright, well thank you guys for at least attempting/looking at it :).

Answer 6

hi!@!

Answer 7

do you have any idea what this looks like? the graph i mean

Answer 8

No. I don't have the slightest idea on how to solve :/

Answer 9

if you know what it looks like, it is easy to solve
the numbers are annoying, so lets change them

Answer 10

vertex \((2,-3)\) directrix \(x=4\)

Answer 11

Mhm.

Answer 12

lets plot those

Answer 13

now do you know what it looks like?

Answer 14

I'm a bit confused..

Answer 15

the fact that the directrix is a vertical line means the parabola opens to the right or to the left (not up or down)

Answer 16

since it is to the right of the vertex, that means the parabola opens to the LEFT

Answer 17

And that makes it negative, right? If that even..goes with this problem lol.

Answer 18

those two facts taken together is enough to pick from you answer choices

Answer 19

So A?

Answer 20

ok scratch that
opens to the left means the Y term is squared

Answer 21

like \(y^2=x\) opens right

Answer 22

and it means the coefficient of the x term is negative

Answer 23

Well that makes it either A or B

Answer 24

no dear i confused you with my mistake
the Y term is squared, not the x term

Answer 25

Oh. Err one sec. So wouldn't that make it D?

Answer 26

the coefficient of the x term is negative

Answer 27

I'm still confused on how you solve for this though..

Answer 28

So the coefficient is the term out side of the ( )

Answer 29

yes, that is the "coefficient"

1) opens to the left or right means y term is squared
2) opens to the left means coefficient of the x term is negative

Answer 30

and the fact that it is a multiple choice question means the answer is C because it is C at least 85% of the time
at least

Answer 31

Alright, I have 2 more directrix problems like this, but I unsure how you determine wether it opens left or right, or up and down.

Answer 32

draw the line

Answer 33

\(x=number\) is a vertical line, opens right or left
\(y=number\) is a horizontal line, opens up or down

Answer 34

But your graph has 2 y's . That's what i'm confused on ^_^

Answer 35

it does?

Answer 36

Unless I am just confused. I am not familiar with your graph. Is it suppose to be a (x,y) graph? Cause to me it looks like (y, x , y)
