Question

What is the graph of x²/9 - y²/25=1

Answer 1

well, is quite obvious is an ellipse

Answer 2

Its an ellipse cutie!

Answer 3

\(\bf \cfrac{x^2}{9}+\cfrac{y^2}{25}=1 \implies
\cfrac{(x-0)^2}{3^2}+\cfrac{(y-0)^2}{5^2}=1\)

Answer 4

So can someon show me how it would look ?

Answer 6

welp, none of my options look like that .

Answer 7

yes, because yours is centered at the origin

Answer 8

so there, draw it

Answer 9

what i am supposed to be drawing ?

Answer 10

an ellipse :)

Answer 11

like in the picture

Answer 12

an oval shape, like an egg

Answer 15

lol okkk. but can i show you my options they gave me ?

Answer 16

ok

Answer 17

ohhh .... wait a sec

Answer 18

I just notice our ellipse turned into a hyperbola
as if someone edited the original material :(

Answer 19

someone, no name, changed the + to - heheh

Answer 20

lol ooohhh. Opss.

Answer 21

idk whats the answer:(. lol ii suck with grapghs.

Answer 22

your graph is fine, for an ellipse, but the + turn into a - heheh

Answer 23

so that makes it a hyperbola
so the values still hold anyway, and so do the coordinates

Answer 24

so it would be the first grapgh?

Answer 25

notice the fraction with the "x" is the positive fraction
so that's the direction the hyperbola is opening, over the x-axis
the vertices are at x= -3 and x= 3
and it opens to the left and right, away from the center
try again :)
