Domain and Range in Functions

The table shows some ordered pairs that belong to quadratic function h. What is the range of h?

• All real numbers

• All real numbers greater than or equal to -7

• All real numbers greater than or equal to -8

• All real numbers greater than or equal to 0

The table shows some ordered pairs that belong to quadratic function h. What is the domain of h?

• All real numbers

• All real numbers greater than or equal to -7

• All real numbers greater than or equal to -8

• All real numbers greater than or equal to 0

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}

Answer.

• A

• B

• C

• D

All of the x values or inputs are called what?

• Domain

• Range

• Relation

• Function

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.
