Is it a Function?
(x, y)
Ordered Pairs are exact locations on the coordinate plane represented by...
{(-4, 7) (-3, 7) (-2,7) (-1,7)}
Which of these IS a function? {(-3, 8) (-3, 9) (-3, 10) (-3, 11)} {(-4, 7) (-3, 7) (-2,7) (-1,7)} {(10, 15), (20,45), (30, 25) (20, 35)}
{(10, 15), (20,45), (30, 25) (40, 35)}
Which set of ordered pairs represents this mapping diagram?
{(-2, -5), (-2,3)}
Which two ordered pairs will not make this a function?
Domain
The set of all input (x) values
Independent Variable
Another term for input
Dependent Variable
Another term for output
Relation
Any set of Ordered Pairs is called a
Only 1 arrow from each value in the left oval (domain)
How you tell a Mapping IS a Function
Domain Values (x's)
In a Mapping, the first oval contains all of the....
Range Values (y's)
In a Mapping, the second oval contains all of the...
1 ONE
In a function, every input (domain) has exactly ___ output (range)
