Relations Lines Functions

This is a one-to-many relation. Is it a function??

• Function

• Not a Function

Illustrates how each element of the domain is paired with an element of the range.

• mapping

• function

• y-coordinate

• x-coordinate

A relation in which each element of the domain is paired with exactly one element of the range.

• function

• relation

• domain

• range

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

• ordered pair

• x-coordinate

• y-coordinate

• discrete graph

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

Determine if the following is a FUNCTION or NOT. If a function state the domain and range.

• FUNCTION : D={Alice, Brad, Carl} R= {snake, cat, dog}

• FUNCTION: D= {snake, cat, dog} R= {Alice, Brad, Carl}

• NOT A FUNCTION

• FUNCTION: D= {Alice, dog, Brad} R= {Carl, cat, snake}

Select which example is the CORRECT mapping for the following:

{(3, 5) (-1, 1) (5, 7) (3,2)}

• A

• B

• C

• D

Determine if the following is a function.

• FUNCTION

• NOT A FUNCTION

Determine if the following is a function.

• FUNCTION

• NOT A FUNCTION
