Rational Functions : Numerator/Denominator                 Close Window
.
Numerator :	Enter a polynomial in x. For instance : x^2+2x-3 or (x-1)(x+3)
.	The numerator can be a rational function itself. For example the expression x-1/(x-2) will be handled appropriately.
.	The Rational Function Plotter can also plot continuous functions by setting the denominator to 1.
Denominator :	Enter a polynomial in x. DO NOT enter zero
.	The denominator can be a rational function itself. The Rational Function Plotter can also plot continuous functions by setting the denominator to 1.

If a graph is needed with a "hole" at x = 2, you must have a numerator and denominator in which the term (x-2) can be thoroughly simplified. See more examples in the Archive section of the site.
