I know how to write the equation of a hyperbola with its two branches (i.e. x^2/a^2-y^2/b^2=1 or vice versa), but can you write the equation of just one branch of the hyperbola? Would it just be the equation of a parabola?
I know you could restrict the domain for those with horizontal transverse axes, but what about for vertical or in general?

Your hyperbola equation is centred at (0,0) so you can restrict the domain as x>0 or x<0.

Thanks, I understand that, but what if the transverse axis is vertical and I only want the top branch?

O.k, you require a hyperbola that opens up top and bottom, which is which is also centred at the origin, you can restrict
