##### Description:

1. To review some vocabulary associated with hyperbolas

2. To learn to graph a hyperbola using its asymptotes as a guide.

This lesson uses a video to demonstrate how to graph a hyperbola which is centered at some point other than the origin. It then provides two practice problems so that students can check their understanding of the concept.

## New Vocabulary

hyperbola:    the name given to the graph of a rational function of the form

y = a/(x - h) + k

branch:        each of the two separate curves that make up a hyperbola

asymptote:  a line that a curve approaches very closely as either x or y gets very                                      large but does not ever reach

## Graphing hyperbolas

This video gives step by step instructions for graphing a hyperbola.

## Examples to Try!

Graph each hyperbola and then check your answers on the following pages.
