Apr 13, 2011the range of a rational function is sometimes easier to find by first finding the inverse of the function and determining its domain (remember that the range of a function is equal to the. Graphing rational functions is discussed in detail in college algebra (mth 111b/c). Here we only wish to get an idea about what happens to the graph of a rational function as the x-values get closer and.

The rational equation we started with produced one answer, = −9. However that one answer is not valid because replacing with −9 results in two of the rational expressions having denominators of zero Example 3 graphing a rational function find the intercepts, cut points and asymptotes and sketch the graph of the rational function

The domain of a rational function is the set of all real numbers, except the zeros of q. Example 1 (a rational function with a denominator that has zeros.) remark 1 all the rules about fractions apply to. Rational functions in this chapter, you’ll learn what a rational function is, and you’ll learn how to sketch the graph of a rational function.

In this section, we explore rational functions, which have variables in the denominator.
