Functions of a Graph and Ordered Pair

An __________ is a pair of numbers used to locate a point on a coordinate plane; the first number tells how far to move horizontally and the second number tells how far to move vertically.

What is a function?

• Any set of ordered pairs

• When each input has two outputs

• When each input has exactly one output

• When the input matches to two different outputs

the output of a function

• x-values

• Dependent Variable

• Independent Variable

• Domain

A set of numbers, or coordinates, written in the form (x, y).

• ordered pair

• x-coordinate

• y-coordinate

• discrete graph

Is this set of ordered pairs a function or not a function? 

• Function

• Not a Function 

The graph of a function is shown. Which three ordered pairs represent an input value of the function with its corresponding output value

• (0, -1)

• (-1, 0)

• (0, 0)

• (-4, 0)

• (0, -2)

The x-value of an ordered pair, represents the horizontal placement of the point. (12, 7) 12 is the x-coordinate

• x-coordinate

• y-coordinate

• discrete graph

• continuous graph

The y-value of an ordered pair, represents the vertical placement of the point.

• y-coordinate

• discrete graph

• continuous graph

• relation

A set of ordered pairs.

• relation

• domain

• range

• mapping

The set of first numbers (x-values) of the ordered pairs in a relation.

• domain

• range

• mapping

• function
