Rational Functions

Make a connection between rational expressions and rational functions. Pupils review simplifying and performing operations on rational expressions and recall what it means for two rational expressions to be equivalent based on their domains. They then learn about rational functions as the quotient of two polynomial functions and identify them and find their domains.
