15. RelaCons
and
FuncCons

16. DefiniCons
RelaCon
à
A set of ordered pairs.
Domain
à
The set of all inputs (x-values)
of a relation.
Range
à
The set of all outputs (y-values)
of a relation.

17. Example
1
RelaCon
à
{ (-4, 3), (-1, 7), (0, 3), (2, 5)}
Domain
à
{ -4, -1, 0, 2 }
Range
à
{ 3, 7, 5 }

18. Example
2
RelaCon
à
{ (-2, 2), (5, 17), (3, 3), (5, 1), (1, 1), (7, 2) }
Domain
à
{ -2, 5, 3, 1, 7 }
Range
à
{ 2, 17, 3, 1 }

19. Example

-1
Relation à {(1, 0), (5, 2), (7, 2), (-1, 11)}
Domain à {1, 5, 7, -1}
Range à {0, 2, 11}

20. DefiniCon
FuncCon
à
A relation in which each
element of the domain ( x value) is
paired with exactly one element of the
range (y value).

21. Are
these
funcCons?
{ (0, 2), (1, 0), (2, 6), (8, 12) }
{ (0, 2), (1, 0), (2, 6), (8, 12), (9, 6) }
{ (3, 2), (1, 0), (2, 6), (8, 12), (3, 5), }
{ (3, 2), (1, 2), (2, 2), (8, 2), (7, 2) }
{ (1, 1), (1, 2), (1, 5), (1, -3), (1, -5) }
