3
Rational Expressions A rational expression is any expression that consists of a polynomial divided by a nonzero polynomial. Examples of rational expressions:
5
Example: Consider the function, determine the following. b) The domain of f (x). a) Graph f (x) in the window:
6
c) Find the zeros/roots for f (x). d) Find the vertical asymptotes.
7
Example Simplify: Solution Factoring the numerator and the denominator. Note the common factor of 9x. Rewriting as a product of two rational expressions. Removing the factor 1 9x/9x = 1, clever form of 1
