Graphing Rational Functions
VIII. Radical Expressions and Equations: Lecture 3 | 45:13 min
In this lecture you will cover Graphing Rational Functions. After covering Rational Functions, our instructor will guide you through Breaks in Continuity which are known as Discontinuities, before covering graph peculiarities such as Hole Discontinuities. Lastly, you will cover Horizontal Asymptotes.

Graphing Rational Functions
If the numerator and denominator have a common binomial factor, the graph will have a hole at the point where this factor is 0. If the denominator has a binomial factor that is not in the numerator, the graph will have a vertical asymptote at the point where this factor is 0.
The graph of a rational function often has a horizontal asymptote.
