dumbcow · Answer

Horizontal hyperbola.
center (0,0)
vertices at (+-3,0)
asymptote looks like y = +- 2/3x

anonymous · Answer

so the full equation is y=+-2/3x?

anonymous · Answer

and which number is that 1

dumbcow · Answer

oh sorry #1, #2,3 are parabolas
no the asymptote is 2/3x not the equation of the hyperbola
use the reference sheet i attached on other post

anonymous · Answer

3)
 Vertex: (2,3) 
vertex equation form is :
x= (y-3)^2 +2

anonymous · Answer

thanks nancy

dumbcow · Answer

2)
vertex at (0,0)
focus point at (2,0)
1/4a = 2
a=1/8

dumbcow · Answer

3)
it opens in negative direction
focus point at (-1,3)
1/4a = -3
a = -1/12

dumbcow · Answer

general equation of horizontal parabola
$$x = a(y-k)^{2} + h$$

anonymous · Answer

isnt it suppose to be y=?

anonymous · Answer

ur answers are kinda wierd

dumbcow · Answer

its y= if the parabola opens up/down
its "x=" if it opens right/left

haha  i know these are weird graphs..but they are correct

anonymous · Answer

ok thanks
