Relation and Functions-                                                              August 16, 2011
OBJECTIVE: SWBAT UNDERSTAND AND USE COMPATIBLE NUMBERS TO ASSIST IN PROBLEM SOLVING

Today we learned what a relation is, what a function is, and the names for "x" and "y". The names for "x" is domain, abscisses, input, and independent; for "y" is range, ordinates, output, and dependent. A relation is a set of ordered pairs. A function is a relation in which each element of the domain is paired with exactly one element of the range. Basically, for every "x" there is only one "y".

EXAMPLE:

If x is a positive integer less than 6 and y=5+x, list the ordered pairs that satisfy the relation. State the domain and range of the relation.

y=5+x    x<6~54321
