Domain & Range

A set of ordered pairs is called what?

• Coordinates
• Relation
• Function
• Vertical Line Test

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

The set of all possible x-values

• Domain

• Range

• Interval Notation

• Inequality Notation

All of the y values or outputs are called what?

• Domain
• Range
• Relation
• Function

What is the domain?

• {-4, -1, 0, 2, 7}
• {-5, -4, -1, 0, 1, 2, 4, 7}
• {-5, 0, 1, 2, 4}
• {5}

What is the range?

• {-3, -1, 2, 4}
• {0, 4, 7} 
• {0, 4, 4, 7}
• {7, 4, 0}

Is the relation a function? Why.

• Yes, because the x-value 11 has two y-values pair with it.
• Yes, because each x-value has only one y-value paired with it.
• No, because the x-value 11 has two y-values pair with it.
• No, because each x-value has only one y-value paired with it.

What is the range of the following relation:
(9, -2) (4, 3)  ( 8, 10) ( -4, 8)

• {-4, 4, 8, 9}
• {-2, 3, 8, 10}
• {(9, -2) ( 4, 3)}
• {(8, 10) (-4, 8)}

For the function (0,1), (1,-3), (2,-4), & (-4,1), which choice gives the correct domain & range?

• D: {0, 1, 2, -4}
  R: {1, -3, -4, 1}
• D: {-4, 0, 1, 2}
  R: {-4, -3, 1}
• D: {0, 1, 2, 3, 4}
  R: {1, -3, -4}
• D:  {-4, -3, 1}
  R: {-4, 0, 1, 2}

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
