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

Rational Function

Definitions Rational function – function defined by a quotient of polynomials

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

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

Example Graph: 1. 2.
