Lesson 8-3: Graphing Rational Functions
Definitions Continuity: graph may not be able to be traced without picking up pencil Asymptote: a line that the graph of the function approaches, but never touches (this line is graphed as a dotted line) Point discontinuity: a hole in the graph
Vertical Asymptote How to find a Vertical Asymptote: x = the value that makes the rational expression undefined *Set the denominator of the rational expression equal to zero and solve.
Point Discontinuity How to find point discontinuity: * Factor completely * Set any factor that cancels equal to zero and solve. Those are the x values that are points of discontinuity
