Unit 8: Rational Expressions & Functions
In this unit, we study rational expressions, equations, and functions. You will learn to simplify, multiply, divide, add, and subtract rational expressions, solve rational equations, understand extraneous solutions, and graph rational functions including asymptotes and holes.
