Find the equation of the hyperbola centered at the origin that satisfies the given conditions: vertex: (0, square root of 12), passing through (2, square root of 3, 6)

A. y^2/36 - x^2/12 =1

B. y^2/12 -x^2/36 =1

C. y^2/6 - x^2/12 =1

D. y^2/12 - x^2/6 =1

Answer 1

D

Explanation:

Answer 2

You know from the y-intercept that the equation will have a +y^2/12 term in it. Then for y=6, you have
.. 6^2/12 -x^2/b = 1
.. 2 = x^2/b
.. b = x^2/2
If your point is (2√3, 6), then this is
.. b = (2√3)^2/2 = 12/2 = 6

Then the hyperbola's equation is
.. y^2/12 -x^2/6 = 1 . . . . . . . . selection D
