Find the Value of a Function (p. 60) 3. Find the Domain of a Function Defined by an Equation (p. 63) 4. Form the Sum, Difference, Product, and Quotient of Two Functions (p. 65) A relation is a correspondence between two sets - a set of ordred pairs. Let X and Y be two nonempty sets. A function from X into Y is a relation that associates each element of X with exactly one element of Y. The set X is called the domain of the function. For each element x in X, the corresponding element y in Y is called the image of x. The set of all images of the elements of the domain is called the range of the function.
