• (-3, 1]

• [-3, 1)

• (-7, 5]

What is the domain of the graph?

• x ≥ 1

• 1 ≤ x ≤ 5

• 1 ≤ x ≤ 4

• x ≤ 5

• All real numbers

Determine the domain & range of the following graph.

• D:{-4, -2, 0, 3, 6}

  R: {-5, -1, 0 , 1, 5}

• D:(-4, 6]

  R: [0, 3)

• D:{-5, -1, 0 , 1, 5}

  R: {-4, -2, 0, 3, 6}

• D:(-4, 6)

  R: (0, 3)

Give the domain and range. Tell if it is a function.

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

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

• D: {-4, -2, 0, 2}
  R: {-2, -2, 1, 1}
  Not a Function

• D: {-4, -2, 0, 2}
  R: {-2, 1}
  Not a Function
