Graph the following conic section
9y^2-4x^2-8x-4=36
Then name(if any) the center, domain, range, vertices, focus point, directrix
***
9y^2-4x^2-8x-4=36
complete the square:
9y^2-4(x^2+2x+1)=36+4-4
9y^2-4(x+1)^2=36

This is an equation of a hyperbola with vertical transfer axis with center at (-1,0)see graph below:
y=(4+(4/9)(x+2)^2)^.5
