Define rational functions and describe their domains. Write rational expressions in lowest terms. Multiply rational expressions. Find reciprocals of rational expressions. Divide rational …

A rational function is a function that can be written as the quotient of two polynomial functions. Many real-world problems require us to find the ratio of two polynomial functions.

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.

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 …

Now that we have a good handle on all of the various operations on rational expressions, we want to turn our attention to solving equations that contain rational expressions. The good news is, …

Write your final answer using the given notation. The power inside the radical must be less than the index. Final answers must have positive exponents.

What is a rational function? A rational function is a function that is a quotient of two other functions. We will usually see this expressed as a quotient of two polynomials. Throughout …
