Given the equation of the hyperbola :

Divide both sides by 144


So, the last result give us the following :
1. the transverse axis will be parallel to y- axis
2. The center of hyperbola = ( 0 , 0 )
3. There is no points of x- intercepts
4. y- intercepts are : y = -3 , y = 3
So, the points of y- intercepts are ( 0 , -3 ) and ( 0 , 3 )
5. Domain = All real numbers
