1. Why is it important to know the domain of a rational expression?

2. Each student in your small group should write down a rational expression in which the degree of the denominator is greater than or equal to the degree of the numerator. Evaluate your rational expression for several “very large” values of x, using a calculator. Discuss your results. Can you predict the approximate value by looking at the rational expression?
