Find the center, transverse axis, vertices, foci, and asymptotes of the hyperbola.(y + 2)2 - 9(x - 4)2 = 9
A. center: (4, -2)
transverse axis is parallel to x-axis
vertices: (-4, -3) and (4, 3)
foci: (4, - 
) and (4, 
)
asymptotes of y + 2 = - 3(x - 4) and y + 2 = 3(x - 4)
B. center: (-4, 2)
transverse axis is parallel to y-axis
vertices: (-4, -1) and (-4, 5)
foci: (-4, 2 - 
) and (-4, 2 + 
)
asymptotes of y + 2 = - 3(x - 4) and y + 2 = 3(x - 4)
C. center: (4, -2)
transverse axis is parallel to y-axis
vertices: (5, -4) and (5, 2)
foci: (5, -1 - 
) and (5, -1 + 
)
asymptotes of y + 2 = - 
(x - 4) and y + 2 = 
(x - 4)
D. center: (4, -2)
transverse axis is parallel to y-axis
vertices: (4, -5) and (4, 1)
foci: (4, -2 - 
) and (4, -2 + 
)
asymptotes of y + 2 = - 3(x - 4) and y + 2 = 3(x - 4)
