domain/range review

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

• D:{0, 1, 2, 3, 4}
  R:{1, -3, -4}

What is the range of the graph?

• 1 ≤ x ≤ 5

• 1 < x < 5

• 1 ≤ y ≤ 5

• 1 < y < 5

What is the domain of the graph?

• 1≤ x ≤ 4

• 1 < x < 4

• 1≤ y ≤ 4

• 1 < y < 4

Does the graph represent a function?

• Yes, because the vertical line test shows there are no repeating input values

• No, because the vertical line test shows there are repeating input values

Does this mapping diagram represent a function?

• No, because there are repeating input values

• Yes, because there are no repeating input values

A relation where every input in matches with exactly one output is called what?

• Relation

• Linear

• Exponential

• Function

Which graph does NOT pass the vertical line test?

• Graph 1

• Graph 2

• Graph 3

• Graph 4

All of the y values or outputs 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.

All of the x values or inputs are called what?

• Domain

• Range

• Relation

• Function
