Algebra 3.2 Maps, Tables and Graphs Name _________________________ Learning Objective: F.IF.1 I will create a map, table, and graph of a function from a relation I will determine if a relation, map, table, or graph is a function I will determine if a sequence is a function I will determine the domain and range of a function in any form I will recognize a sequence is a function I will find the domain from a graphed function, a relation, or a mapping F.IF.1 F.IF.1 F.IF.1 F.IF.3 F.IF.5 Are the following graph functions? 1. 2. Function? 3. . Function? 4. Function? Function? Express each relation as a set of ordered pairs. Then find the domain and range and determine if the following graphs are functions. 5. 6. {(–4, 2) (5, 2) (4, 6) (6, 5)} Ordered pairs: Domain: Domain: Range: Range: Function: Function: Express each relation as a set of ordered pairs. Then find the domain and range and determine if the following graphs are functions. 7. x 4 – 1 0 1 y – 5 – 10 – 9 – 7 8. Ordered pairs: Ordered pairs: Domain: Domain: Range: Range: Function: Function: 9. Name the ordered pair at point B and explain what it represents. 10. Name the ordered pair at point C and explain what it represents. Express each relation as a graph, a mapping, and a table. Then state the domain and range and determine whether it is a function. 11. {(5, 2) (5, 6) (3, –2) (0, –2)} Domain: x y x Range: Function? 12. {(–1, 3) (3, –6) (–1, –8) (–3, – 7)} x Domain: y Range: Answers: 1) no 3) no 5) {(–1, 2)( 0, 3)( 3, 2)(3, –2), {–1, 0, 3}, {2, 3, –2}, no 7) {(4, –5)( –1, –10)( 0, –9)(1, – 7), {4, –1, 0, 1},{–5, –10, –9, – 7}, yes 9) (5, 25) Walking 5 dogs will earn you $25. 11) D: {5, 3, 0} R: {2, 6, –2} no Function? y
