1. Lesson 1 Notes – Graphing Rational Functions
-To graph rational functions

2. Rational Function

3. Definitions
Rational function – function defined by a quotient of polynomials

4. Asymptotes
Vertical asymptote – vertical line which the graph approaches but never touches (where x is undefined) In rational equations: x = h is the equation for the vertical asymptote

5. Asymptotes
Horizontal asymptote – horizontal line which the graph approaches but never touches In rational equations: y = k is the equation for the horizontal asymptote

6. Example
Graph: 1. 2.
