Answer 9

OMG This Website Is A JOKE!

Answer 10

I'm here

Answer 11

Sorry, was busy irl

Answer 12

Thank God! Lol

Answer 13

One moment, I'm refreshing my memory *hasn't done this in a while* I'll be right with you

Answer 14

Ok

Answer 15

So, your focus is 1, where y=term a in the general form of a parabola:
y^2=4ax or x^2=4ay

Answer 16

The Answer Should Be Something Like f(x)=x over x x^2
X Will Be Replace By Numbers Of

Answer 17

Course

Answer 18

There is an equation button just below the comment box. I want to be sure that I interpreted that result of yours properly, so would you mind typing it into that?

Answer 19

Like That

Answer 20

Why Wont It Let Me Insert

Answer 21

\[f(x)=x/(x(x^2))\]

Answer 22

Like that?

Answer 23

Its f(x)= (fraction) (x- or + 2)^2+6 or 8

Answer 24

From who or where did you get this equation(s)? What makes you think that this is the answer?

Answer 25

FLVS

Answer 26

Okay, so they'll want the answer in that format...
The thing is, that doesn't resemble the equation that I believe it to be. And I don't know if I can cater my formula into that format, simply because the numbers don't look right.
Would you like to try my method, or find someone from FLVS to do it in your method?

Answer 27

Try Yours

Answer 28

Alright then, I'll keep it as simple as possible. The vertex isn't given,but since there aren't any intercepts or such given, it's safe to assume that the vertex is the origin
Because the focus is 1, and the directrix is -1, we know that p from x^2=4py is equal to 1

Answer 29

The directrix is a line never touched by the line of the equation, so we know that the equation opens upwards
