Review for Chapter 2 Test

For the function {(0,1), (1,-3), (2,-4), (-4,1)}, write the domain.

• 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 domain of the graph?
Remember:   Domain is the "x" values from left to right

• -7 ≤ x < 5
• -3 ≤ x < 1
• -3 ≤ y < 1
• -7 ≤ y < 5
