Algebra 2/Trigonometry 2. 1 Domain & Range of Graphs Name: _______________ Date: _______________ Relation – __________________________________ Domain – __________________________________ Range – ___________________________________ Function – __________________________________ To determine if a relation is a function you can either look at the mapping of a set of points or use the Vertical Line Test. 1. ) Function? YES NO 2. ) Function? YES NO Vertical Line Test – Is the graph a function? DOMAIN OF GRAPHS To determine the domain of a function, think about what x-values are possible … Most of _____________________________________________________________________ Meaning ______________________________________________________________________ There are three exceptions: 1) _______ 2) _________ 3) _________ Implied Domain – ____________________________ When the domain is “undefined”: ______________________ Domain & Range Interval Notation Parenthesis – _________________________________________________________________ Bracket – _______________________________ Union – ________________________________ ** domain and range can also be expressed as an inequality, but we will stay consistent and always use interval notation
