Unformatted text preview: 3.6 Functions MartinGay, Beginning and Intermediate Algebra, 4ed 2 Relations, Domain, & Range A set of ordered pairs is called a relation . The set of all xcoordinates is called the domain of a relation. The set of all ycoordinates is called the range of a relation. MartinGay, Beginning and Intermediate Algebra, 4ed 3 Find the domain and range of the relation {(4,9), (4,9), (2,3), (10, 5)}. The domain is the set of all xvalues: {4, 4, 2, 10}. The range is the set of all yvalues: {9, 3, 5}. Example: Domain and Range MartinGay, Beginning and Intermediate Algebra, 4ed 4 Find the domain and range of the graphed function. Use interval notation . x y Domain: [ 3, 4] Domain Range: [ 4, 2] Range Example: Domain and Range MartinGay, Beginning and Intermediate Algebra, 4ed 5 Find the domain and range of the graphed function.
