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)

Table, Graph, Ordered Pairs, Map

The 4 ways to represent a Relation are...

Range

The set of all output (y) values

Is

This Relation _____________ a Function (1,4) (2,4) (3,4)

4

What is the range? {(-3, 4), (-4, 4), (-5, 4)}

When a Domain (x-value) repeats with a different Range (y-value)

When is a relation NOT a Function?
