Please Help!!! Easy conic section question! 1. Graph each equation. Identify the conic section and its lines of symmetry. Then find the domain and range. 2. x^2 - y^2 - 9 = 0 3. I have no idea how to do this. I know it's a hyperbola because i solved for "y" and graphed it in my calculator, but i have no idea how to find the domain/range and values. Help!!
