Look no further! 2 0 obj A function is a statement defining a single result for each question, or a single output of each input. 4. PDF RELATIONS & FUNCTIONS Worksheet - School For Excellence Ans. The first 3 questions ask students to take a relation (given as a set of ordered pairs) and represent the relation as a table, graph, and mapping diagram. A relation is established between two sets when an object from one set is related to one object from another set, resulting in the formation of ordered pairs. The students look at 20 different x y tables and decide rather the ordered pairs form a linear or nonlinear relationship. lOma`M<?L;l"=8o/+}V[*v"WmO%2loCe^Tj.I;e?&){wv Oex`aWgd{D0m:ZL/.]VY-+
