2. Ex 1) Graph xy = 4 Solve for y: Make a table: xy 2 4 8 1 1 ½ 4 2 -4 -8 -½ -4 -2 Doesn’t touch y -axis Doesn’t touch x -axis x -axis and y -axis are Asymptotes! It’s a …. Hyperbola!!

3. Conic Sections

4. Identifying Conic Section from Equation Parabola: Circle: Ellipse: Hyperbola: Line: Only 1 squared term 2 squared terms, (+) & Coeff = 2 squared terms, (+) & Coeff ≠ 2 squared terms, (–) No squared terms 1 OR xy = #
