Question

What are the foci of the following graph?
Answers:
(-3, 0) and (3, 0)

(0,- sqrt 27 ) and (0,sqrt 27 )

(0, -6) and (0, 6)

(-6, 0) and (6, 0)

Answer 1

I got A as my answer

Answer 2

foci lies on major axis

Answer 3

which is y axis here

Answer 4

Answer 5

so you must have foci coordinates as : (0, k) (0, -k)

Answer 6

I meant (0,±sqrt(6² - 3²)
The foci are always sqrt(a²-b²) away from the center.

Answer 7

use the formula for k = \(\sqrt{a^2-b^2}\)

Answer 8

So its b then

Answer 9

correct
