This chapter deals with functions that have the variable in the denominator of a fraction. First, we will discuss the concept of variation and how that relates to a rational function. Next, we will graph several different types of rational functions followed by multiplying, dividing, adding, and subtracting rational expressions. Lastly, we will solve rational equations.
This chapter covers variation, graphing rational functions, simplifying, multiplying, dividing, adding and subtracting rational expressions, and solving rational equations.
