Identify Domain from Functions

Identify the domain of the following relation:

• {-6, 14, 2, 28}

• {(-6,14), (0,32), (2,38), (4,44)}

• {-6, 0, 2, 4}

• {14, 32, 38, 44}

What is the domain of the graph?

• y≥1

• x ≥ 1

• All real numbers

• none of these

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}

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

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
