Question

Which is the Equation shown by the graph?

Answer 1

do you know the standard form of ellipse ?

Answer 2

no

Answer 3

\[\huge\rm \frac{ (x-h)^2 }{ a^2 } +\frac{ (y-k)^2 }{ b^2 }\] standard form of ellipse
if a is under the x then it would be horizontal
and if a is under y then graph would be vertical

Answer 4

by just looking at the standard form of the equation you can eliminate 2 answer choices

Answer 5

so it is vertial

Answer 6

yes right

Answer 7

which two are eliminated then?

Answer 8

\[\huge\rm \frac{ (x-y)^2 }{ a^2 } - \frac{ (y-k)^2 }{ b^2 }\]
this is standard form equation of *hyperbola*
only difference is the sign between both fractions

Answer 9

and sorry i forgot to tell
a=always bigger than b

Answer 10

im still confused on what the answer is though

Answer 11

reread my comments you will get the answer :=)

Answer 12

...no..

Answer 13

idk what a stands for

Answer 14

do you know the difference between ellipse and hyperbola graph ?

Answer 15

no

Answer 16

a represents bigger number

Answer 17

do you know anything about ellipse equations ?

Answer 18

nope

Answer 19

surprising

Answer 20

...why

Answer 21

bec you don't know the introduction of conic section which supposed to be ur h.w

Answer 22

\[\huge\rm \frac{ (x-y)^2 }{ a^2 } - \frac{ (y-k)^2 }{ b^2 }\]
this is standard form equation of *hyperbola*
that's how the graph looks like

Answer 23

I just asked for help, if you aren't going to help please don't waste my time I just wanted to learn how, not be insulted with sarcasm thank you.

Answer 24

and here is graph of ellipse equation \[\huge\rm \frac{ (x-y)^2 }{ a^2 } \color{reD}{+} \frac{ (y-k)^2 }{ b^2 }\]

Answer 25

i'm not insulting you
sorry if you take it that way.

Answer 26

so now can you find the difference between both equations ?

Answer 27

and sorry i asked few questions so i can get an idea where to start
sorry if u mind..

Answer 28

i got x^2/4+y^2/16=1

Answer 29

hm
given graph of ellipse is vertical right ?

Answer 30

yeah

Answer 31

yes right so bigger number should be under the y value and
there is plus sign so that's right!

Answer 32

thank you for your help

Answer 33

my pleasure.
B and D can't be the answer bec those 2 are hyperbola equations
