### Project in math

1. 1. Project InMathematics IV
2. 2. Whatis aRelation?
3. 3. Relation• It is any association between elements of one set• The domain can’t be repeated so that it can be called a function
4. 4. Different Ways ofExpressing RelationArrow DiagramTabular MethodGraphical Representation
5. 5. ARROW DIAGRAMWe write the elements from thedomain on one side, and theelements from the range on theother, and we draw arrows to showthat an element from the domain ismapped to the range.
6. 6. ARROW DIAGRAMkinds of expressing the arrowdiagram. -One to one -Many to one
7. 7. ONE TO ONE Loves Bryan Zenith Loves Paolo Ronalyn
8. 8. ONE TO ONE In this diagram we illustrate thatBryan loves Zenith and Paolo lovesRonalyn.In the coordinates it can be this: (Bryan,Zenith) and (Paolo,Ronalyn) Where Bryan and Paolo are thedomainwhile Zenith and Ronalyn are the range.
9. 9. MANY TO ONE Loves Bryan Zenith Loves Paolo Ronalyn Arjay Mary
10. 10. MANY TO ONE In this diagram we illustrate that Bryanloves Zenith, Paolo loves Ronalyn again. Younoticed that there are newCharacters appeared on the diagram. And thatis Arjay who loves Zenith, andMary who loves herself.So the coordinates are:(Bryan, Zenith) (Paolo, Ronalyn)(Arjay, Zenith) (No one, Mary)
11. 11. ARROW DIAGRAMReminder!:In writing an arrow diagramThe x or domain should NOTBe repeated or else it will not be afunction. While the y or range CANbe repeated.
12. 12. TABULAR METHODIt is a set is represented by writing allthe elements of the set, separated bycommas and are enclosed withinbrackets { }
13. 13. GRAPHICAL REPRESENTATIONBy showing the relation is by makinga graph.
14. 14. GRAPHICAL REPRESENTATIONWhen graphing a point you should knowif that is a function.-Use the vertical lines that will travel inthe path of the line. If the vertical linetouches another line of the coordinatesthat will not be a Function.
15. 15. GRAPHICAL REPRESENTATIONFor Example:
16. 16. GRAPHICAL REPRESENTATIONYou’ve seen that the vertical linePassed through the line without touchesanother line. And can becalled a function
17. 17. EVALUATION-Just click the letter of thebest answer!-No returning back!-Click only the Arrowbutton at the right side tonext the slide.
18. 18. EVALUATIONWhich of the following is not a way ofexpressing a relation?A. Tabular Method B. Arrow DiagramC. Table Method D. Graphing Representation
21. 21. Which of the following arethe kinds of expressing theArrow Diagram so that it canbe called a function? A. (One to One) and (One to many) B. (One to Many) and (Many to One) C. (One to One) and (Many to One) D. (No answer) and (No answer)
24. 24. Which of the followingrelation is not a function? A.(2,3) and (2,3) B.(3,3) and (2,2) C.(4,3) and (2,4) D.(5,3) and (15,3)
