  1. Unit 2, Lesson 3 - textbook section 4.3 & 4.6 Sept. 27, 2010 RELATIONS and FUNCTIONS DOMAIN and RANGE

  2. A relation is a pairing between 2 sets of numbers A relation can be represented in a variety of ways: A SET OF ORDERED PAIRS TABLE GRAPH MAPPING WE'VE SEEN ALL OF THESE THIS YEAR EXCEPT A MAPPING.

  3. Write these words down: Domain and Range Domain: the independent variable Range: the dependent variable

  4. The domain is also the set of all inputvalues. The range is the set of all the outputvalues. The inverse is when you flip the domain and the range. C. WRITE THE INVERSE OF THE RELATION ABOVE. C. { ( 3, 4) , (-1,-2) , (-4, 2) , ( -4, 0 ) }

  5. CLASS PRACTICE - See handout 1st - Draw the missing representations. 2nd - List the Domain and Range.

  6. HOMEWORK PRACTICE WORKBOOK SECTION 4-3 (PW 4-3) ALL PROBLEMS

  7. Ordered Pair { (-2,1) (0, -1), (2, 1) } REVIEW OF YESTERDAY'S LESSON The domain is also the set of all input/independentvalues. The range is the set of all the output/dependentvalues. The inverse is when you flip the domain and the range.

  8. A function is a special type of relation. It is a pairing between two sets of numbers in which each element of the first set is paired with EXACTLY one element of the second set In other words, for every DOMAIN there is one RANGE. Example:

  9. CLASS WORK - see handout

  10. If given a value for the domain, how do you find the range?

  11. HOMEWORK - PW 4-6 # 1-7 ALL # 8-12 EVEN
