1. Hyperbolas Objective: graph hyperbolas from standard form

2. Review Circles Standard Form Center Radius Ellipses Standard Form Center Vertices Foci Major and Minor Axes

3. Hyperbolas Definition: Locus of points such that the difference of the distances from 2 fixed points is constant Standard Form of Equation: or

4. Parts of a Hyperbola

6. Example Graph center: (0, 0) a = 4 b = 5 vertices: (4, 0) (-4, 0) slope of asymptotes: + 5/4 foci: (+ √41, 0)

7. Practice Graph the hyperbola

8. Practice Graph the hyperbola 9x 2 – 4y 2 – 54x – 40y – 55 = 0.
