In this lesson, we will learn how to simplify rational functions and how to find their domains.

Students will be able to

simplify rational functions by finding and eliminating common factors in the numerators and denominators,
state the domain of a rational function by considering values of for which the denominator is equal to 0 (including a function that can be simplified),
identify when two rational functions are equivalent,
identify the common domain between two functions that reduce to the same simplified form,
recognize when two rational functions are equivalent for values in their common domain.
