Introduction to Relations and Functions

In the given relation, what domain value corresponds to the range value -2?
{(-1,2), (-2,4), (2,5), (0,-2), (2,0)}

• -2

• 0

• 2

• 4

For the function {(0,1), (1,-3), (2,-4), (-4,1)}, write the domain and range.

• D: {1, -3, -4,}

  R: {0, 1, 2, -4}

• D:{-4, 0, 1, 2}

  R:{-4, -3, 1}

• D:{0, 1, 2, 3, 4}

  R:{1, -3, -4}

What is the type of the relation?

• One-to-one relation

• One-to-many relation

• Many-to-one relation

• Many-to-many relation

Relations that is a FUNCTION is

• One-to-one relation

• One-to-many relation

• Many-to-many relation

• All of the above relations

Which mapping diagram is not a function?

• 
• 
• 
• 

What is the type of the relation?

• Many-to-one relation

• One-to-one relation

• Many-to-many relation

• One-to-many relation

What is the definition of function?

• Has inputs and outputs

• Every input has only ONE output

• Inputs have different outputs every time

• x-values and y-values

This relation is called
